WebHow is the Molarity of a percentage solution calculated? Using 70% concentrated nitric acid as an example: 70% nitric acid means that 100 grams of this acid contains 70 grams of HNO 3.The concentration is expressed at 70% wt./wt. or 70 wt. % HNO 3.Some chemists and analysts prefer to work in acid concentration units of Molarity (moles/liter). WebSo we take the mass of a large number of molecules and express it in grams. This number is a fixed but very very large number called “mole”. 1 mole = 6.023 x 10^23 (or 602300000000000000000000) When you say that the molar mass of water (H2O) is 18 grams per mole, you mean that 1 mole of water molecules weigh 18 grams.
