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...
In a previous video by NurdRage, he showed you how to make manganese sulfate ("How to make MnSO4 from MNO2 (two separate ways)"), but there can be situations where the iron in the precursor would carry over and contaminate the product. Recrystallization doesn't work for this high level of contamination, so a different approach is needed.

When you have to find the average of two or five numbers then you have to add all the numbers and then divide then by two or five respectively. However in the case of the function you have infinite many values over any interval. But it is not possible to add all and then divide by infinity. Therefore you have to calculate in a different way. Imagine that you have to find the average of y=f(x). Then you have to average it from the interval from ‘a’ to ‘b’. The inner area under the curve shall ...

In this video, Mr. Maisonet provides a quick and easy method for calculating the area of a trapezoid. In the first step, The lengths of the two bases (the two sides of a trapezoid that are parallel to one another) are averaged. The lengths of the bases are first added together, and the sum is divided by two, yielding the average. The average is then multiplied by the height. The resulting product is the area of the trapezoid. This method for finding the area of a trapezoid is mathematically s...
