The combustion of hydrogen and oxygen is commonly used to

power rocket engines:

2H2 (g) + O2 (g) → 2H20 (g)

If the final pressure of water vapor was 0.875 atm and the

temperature is 400. K, how many mols of H2O was produced

assuming that the reaction went to completion in a 250. L

engine?

6.66 mol

Explanation:

(atm x L) : (0.0821 x K)

(0.875 x 250) : (0.0821 x 400)

=6.66108
