Answer:

48 grams O2 and 6 grams H2

Step-by-step explanation:

This is chemistry as well but it's fine.

If you have 3 moles of H20, you need 1.5 moles of O2 and 3 moles of H2, to satisfy the stoichiometry.

There are 32 grams in 1 mole of O2, so 1.5 moles of O2 is 48 grams.

Their are 2 grams in 1 mole of H2, so 3 moles of H2 is 6 grams.
