a) molar mass H₂ = 2.0 g/mol m = n * mm m = 15.0 * 2.0 m = 30.0 g of H₂ _________________________   b) molar mass N₂ = 28.0 g/mol m = n * mm m = 3.5 * 28.0 m = 98.0 g of N₂ ____________________________ c) molar mass of NaOH = 40.0 g/mol m = n * mm m = 2.69 * 40.0 m = 107.6 g of NaOH _____________________________________ hope this helps!
