How To: Use color passes and add masks using Premiere Pro

Sin City used some of the coolest visual effects of any recent film. This two-part video uses a clip from the iconic film as an canvas to which we can apply some other editing effects using Adobe Premiere Pro. Specifically, the first part covers using color passes to absorb colors and adding a mask to focus the color spot. The second covers animating a garbage matte with keyframes and other topics. Unfortunately there is no link for downloading the Sin City clip from the video, so you are goi...

How To: Find percent by mass & percent composition

In chemistry you come across problems which ask you to find the percent by mass and percent composition of each element in a chemical compound. To do this the first step is to compute the molar mass. Use the periodic table to look up the mass of individual atoms and multiply it by the number of atoms to find the mass of that element. Now add up all the masses to arrive at the molar mass of the compound. Now to find the percent composition of an element divide the total mass of each element by...

How To: Convert grams to moles for chemistry

310tutoring shows viewers how to easily convert Grams to Moles for Chemistry. If you have 120 grams NaOH and we want this in moles we need a periodic table. Now, you need to figure out what the mass is of each individual element in NaOH. You need the mass of Na, O and H. Na mass is 23, O has 16 and H is 1. Add all of these up to get the molar mass of NaOH is 40 g/mol. Now use this to convert 120 g to moles. Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel...

How To: Calculate weighted atomic mass

This video is about Level 2 atomic concepts, specifically the Pennium Lab. This helps you understand how atomic masses are derived for the periodic table. This teacher demonstrates how to do the calculation. He first reviews the Isotopes as they are different masses of the same type of atoms. He uses chromium as his example. It has a different number of neutrons in the nucleus. Using the equation, it could have either 26, 28, 29 or 30, with its 24 protons. So he subtracts the atomic number fr...

How To: Find density using the water displacement method

To find out the density of any given object there is a simple equation, mass divided by the volume equals the density. In this video a lady is showing how to get the volume of three objects using water. First the objects are measured on a scale to find out how much they weigh, the mass. Next each one of the objects is placed into a measured amount of water to find out the volume. Before you place the object into the water you will want to know just how much water in there. That way when the o...

How To: Calculate and understand the concept of molar mass

Two college students; Kevin Martin and Joey Smokey introduce the concept of Molar Mass. They start of by explaining what molar mass is, which is the relationship of a mole and a gram, it totals up the weight(in g)of a molecule. An example: say you have this compound, Sodium phosphate (Na3PO4). You know you have three sodium atoms, one phosphorus atom, and four oxygen atoms. You basically find the weight of each atom, if you have three sodium atoms, you multiply it's atomic mass by 3 (the numb...

How To: Find molar mass

It’s time for science. You are able to calculate the molar mass for a compound using the periodic table and the amount of compound involved. You might need to know this in your everyday life but you will definitely need this in a chemistry class.

How To: Calculate weight if given the mass

The video shows how to calculate weight if the mass is given and vice versa.Later on in this unit you will learn about Newton's laws of motion and Newton's second law of motion gives us a way to change mass into weight and vice versa.This law will tell you what is happening to objects when the net force on the object is not equal to zero and the easy way to say what will happen is that the object will accelerate.But how much the object accelerates depends on two things,firstly the mass of the...

How To: Calculate weight average atomic mass of an element

In Chemistry weight of some elements are measure in the form of Average Atomic Mass. Isotopes are found in different abundances in nature. Certain elements have many isotopes and certain elements have few isotopes. Regardless of the number of the natural isotopes, the weighted average mass takes into consideration not only the mass of each isotope, but what also its natural abundance in terms of percent as found in the nature. So when you have the mass of two isotopes of an element and are gi...

How To: Choose the best character class in Mass Effect 2

Been craving some epic space action lately? Well charge up the mass relays and practice your conversation skills because Mass Effect 2 is finally here. In today's episode of IGN, you will learn how to start the game off right and pick the best character for you. This video will walk you through all the different characters so you know exactly who you want to choose to embark on your journey with.

How To: Understand Newton's second law

In this tutorial the author explains the concept of Newton's Second Law of motion which states that force is equal to mass times acceleration. So the equation to compute force F is F = m * a, where m is the mass of the body and a is the acceleration produced by the force on that body. He explains that even our weight is our mass times the gravity. So now he explains that mass of a body is constant and only our weight changes depending up on the situation we are in. If you want a clear underst...

How To: Draw a horse

In this video, we learn how to draw a horse. First, draw the outline of the horse's body. Start with a circle for the head and wispy lines for the rest of the body. Make large shapes that connect to see where the mass of the body will be. Next, draw in the head, tail, back, and legs of the horse. After you have the outline finished, erased the lines inside of the picture. Now, draw in details on the horse. Add in lines to show where the hair is, then draw in the nose and eyes to the face. Als...

How To: Draw a female eye using Photoshop

In this video tutorial, viewers learn how to draw a female eye using Photoshop. Begin by creating a rectangular box. This will contain the eye. Now draw the shape of the eye in the box. Now add in the details. Draw in the shape, eyelashes, eye brows, eye lids and eye ball. When drawing the lashes, draw them as a mass instead of individually. Then add the eye lids with a few lines above the eye. Then draw two circles for the eye (eye ball and pupil). This video will benefit those viewers who e...

How To: Make homemade playdough for kids

To make homemade play dough you first need to mix all of you ingredients together in a pan staring with two cups of flour and two cups of warm water. Next you add about one cup of salt, two table spoons of vegetable oil, and one table spoon of cream of tartar. After that you stir it until it looks like pancake mix.
