Question

Calculate the ratio by number of atoms in water molecule (mass ratio of H2O In water is 1:8)

Answer 1

Answer:

The ratio of hydrogen and oxygen by mass in water is 1:8. The atomic masses of H and O are 1 g/mol and 16 g/mol respectively. In H2O, the ratio of hydrogen and oxygen by mass will be 2:16=1:8

Answer 2

Answer:

molecular mass 1:8
