Determine the mass of nitric acid with the amount of the substance 15 mol.

Nitric acid formula: HNO3. The mass can be found by the formula m = n * M, where n is the amount of substance, mol, M is the molar mass of the substance, g / mol (determined by the periodic table). The mass of the acid m = 15 mol * 63 g / mol = 945 g.
Answer: the mass of 15 mol of nitric acid is 945 g.
