The mass molarity calculator tool calculates the mass of compound required to achieve a specific molar concentration and volume.
(moles/liter). To calculate the molarity of a 70 wt. % nitric acid the number of moles of HNO3present in 1 liter of acid needs to be calculated. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO3to be 1413 grams. Knowing that ...
