Using 2 H2 + O2 → 2 H2O

If 3.00 moles of H2O are produced, how many grams of oxygen must be consumed?

Using the given from problem two, how many grams of hydrogen gas are used?

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.
