  • The molar mass of water is 18.015 g/mol. This was calculated by multiplying the atomic weight of hydrogen (1.008) by two and adding the result to the weight for one oxygen (15.999) Mass of one molecule of water = Molar mass / NA = 18/ NA g Avogadro number(NA) =6.022 x 1023mol¯1 There are 8 neutrons in one atom of oxygen
