WebLet us start by calculating the formula mass of sodium chloride (NaCl). This formula mass is the sum of the atomic masses of one sodium atom and one chlorine atom, which we find from the periodic table; here, we use the masses to two decimal places: Na: 22.99 amu Cl: +35.34 amu Total: 58.44 amu WebStep 1: Calculate the molar mass of water. We know that molar mass of 1 mole of Hydrogen is 1 g mol - 1. and, molar mass of 1 mole of Oxygen is 16 g mol - 1. We know that the chemical formula of water is H 2 O. ∴ molar mass of water is. H 2 O = 2 × 1 + 16 = 2 + 16 18 g mol - 1. Therefore, molar mass of water is 18 g mol - 1. Suggest Corrections.
