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
