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. WebSolution. Verified by Toppr. Correct option is A) Relative molecular mass for water (H 2O) =2× relative atomic number for hydrogen +1× relative atomic number for oxygen. =2×1+1×16. =18. So, relative molecular mass for water is 18. Solve any question of Structure of Atom with:-.
