How to Calculate the Number of Moles of an Element Chemistry
WebThis video explains how to calculate the number of moles of an element given the mass, as well as how to calculate the mass given the number of moles. WebThe most common way to express solution concentration is molarity (M), which is defined as the amount of solute in moles divided by the volume of solution in liters: M = moles of solute/liters of solution. A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution. Created by Sal Khan.
