WebJan 3, 2024 · concentration = number of moles / volume Molarity formula The following equation allows you to find the molarity of a solution: molarity = concentration / molar mass The concentration denotes the mass concentration of the solution, expressed in units of density (usually g/l or g/ml). Molar mass is the mass of 1 mole of the solute. WebHowever, this problem asks us to solve for the number of moles of gas, or n. To do this, you can solve for n in the equation as Sal did, and get n = PV / RT. Here, you can see that to get n, we multiply pressure and volume, and then divide by temperature and R.
