Answer: 0.463 mol (to 3 sf)

Explanation:

  • The atomic mass of hydrogen is 1.00794 g/mol.
  • The atomic mass of water is 15.9994 g/mol.

So, the mass of water is 2(1.00794)+15.9994 = 18.01528 g/mol.

This means that in 8.35 grams of water, there are:

  • 8.35/18.01528, which is 0.463 mol (to 3 sf)
