QUESTION

# What is the mass of one mole of water?

18 grams

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
