Web19 de ago. de 2024 · Mass of H 2 O in 1 mol hydrate = 108.12 g Molar mass of hydrate = 237.95 g/mol Unknown percent H 2 O = ?% Calculate the percent by mass of water by dividing the mass of H 2 O in 1 mole of the hydrate by the molar mass of the hydrate and multiplying by 100 %. Step 2: Calculate. % H 2 O = 108.12 g H 2 O 237.95 g × 100 % = … 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.
