We'll learn how to use moles to figure out how many atoms you have in something. If there are 602 hexillion things in a mole, how do you count them all? By using the periodic table, you can figure out the molar mass, the amount that one mole of a substance weighs. Once you weigh something to determine how many moles are in it by using molar mass, Avogadro's number allows you to figure out how out how many atoms there are.

$Mole Fraction Introduction This video is an introduction to mole fraction. Mole fraction is one of the ways that we can describe or measure the concentration of different components in a mixture. It is calculated by dividing the moles of the component of interest by the total number of moles in the mixture. This video is for students in both high school and college/university. It will also be helpful to people who are preparing for the following curricula and exams: AP, SAT, IB, A-levels, O-levels, IGCSE, ICSE, CBSE, MCAT, DAT, OAT, JEE, NEET$
