The way to convert 0.300 Moles of water into Grams is to start by writing what you have. Then put grams on top and moles on the bottom, then put one by the mole, the omler mass goes by grams. Now you figure out the moler mass of water which has 2 H and 1 O, its 2 times 1 which is the atomic mass for hydrogen plus 16.0 for oxygen which gives a total of 18.0 g/mol. So then you insert the 18 up by the grams, now you can cancel out the moles and multiply 0.300 times 18.0g and it gives you 5.40 g,...
This video shows the viewer how to start a fire using char cloth and a fire steel. Char cloth is a fabric which burns/smolders very slowly. This makes it very useful for starting fires. The video suggests gathering dried grass. The smoldering chard cloth should then be placed in the middle of the grass. Blowing gently on the char cloth will increase the oxygen reaching the flame so will increase the chances of success. Waving the bundle of straw should also help. Remember to always wear glove...
In this video, Yuri Elkaim will teach you how to get six pack abs using cardio and strength training. He breaks down the discussion of cardio vs. strength training for burning fat and building muscle. In the video, Elkaim stresses high-intensity interval training (HIIT), in which he says you will burn more calories, and therefore lose more fat if that is your aim. Furthermore, working at a higher intensity for longer periods of time increases your cardiovascular strength to an even higher deg...
Ever wondered how science could turn out to be fun? Here's how: take a piece of paper with a mixture of sodium nitrate and sugar. When heated, sodium nitrate releases oxygen and burns sugar. Sugar alone cannot burn fast. If you want faster results, then take sodium nitrate with sulphur and some reactive metals. Add some coal to it for a faster result. This will help you burn some useless pile in quick time.

In this video, we learn how to make your own charcoal. First, you want to make a stack of wood you have laying around, anything you have from scraps. Now, push the wood into a small empty pant can until you cannot fit anymore. Then, place the top onto the can so no oxygen gets into the can. After this, load the cans into a large barrel that has large air holes in it, then wait for the wood to turn into charcoal! This is a process that does take a long time and when finished, the can is going ...

Bioluminescence — the ability of an organism to produce and emit light — is nature's light show. Plants, insects, fish, and bacteria do it, and scientists understand how. Until now, though, we didn't know how fungi glow.
I own two aprons—a cute one for company, and another for the hard-core cooking duties, like cutting up chicken and making stock. The sad truth is that I almost never remember to wear either of them. So, much of my clothing ends up spattered with grease, liquid, and bits of fruit and vegetable. While stain-removing sprays, sticks, and pens are all effective to a certain extent, they have two drawbacks—they're expensive and sometimes I need to use them in large quantity, like when a piece of eg...
Many of us experience highly emotional "freakouts", so to speak, more often than we'd like. Weather you experience them personally, or via your loved ones, it can be very difficult to think rationally during an episode, and for some people it can take quite a while to calm down.
Bad news, guys. The shelf life for liquor leftovers does not apply to your two-buck chuck. While an opened bottle of your favorite whiskey will stay respectable for ages thanks to its high ABV (which makes it inhospitable to outside elements), an opened bottle of merlot will sour quickly. However, it turns out that red and white wines have different life spans once they're opened—for reasons which we'll cover below.
