Calculate the mass of 1 molecule of water
WebJan 4, 2016 · Explanation: The mass of one mole of any atom/molecule is equal to its atomic molecular mass in grams. The molecular formula of water is H 2O. The atomic mass of H = 1. The atomic mass of O = 16. In a sense, the formula means H + H + O. So... 1 + 1 + 16 = 18. Therefore, the mass of one mole of water = 18 Grams.
