D, 18.02 g/mol

Danny Yoder · Answer 2

D. 18.02 g/mol

Explanation:

Molar mass of any element is equal to the atomic mass of that element in the unit of grams. Molar mass is also equal to the mass of 6.02*10^23 atoms of that element.

The water or H2O is formed from 2 mole of hydrogen and one one of oxygen

The molar mass of H = 1.008 g / mole

The molar mass of O = 16.00g / mole

Therefore the molar mass of water = 2 * 1.008 g / mole+16.00g / mole
