You are asked two questions and you need two answers:
1) The chemical formula for water is H2O which shows that the two elements needed to combine are Hydrogen and Oxygen.
2) The proportion of the two elements needed, is also shown by the formula. This is 2 /1 Hydrogen / Oxygen by volume, or 2 /16 by weight.
