Question

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?
mol

Answer 1

6.66 mol

Step-by-step explanation:

(atm x L) ÷ (0.0821 x K)

(0.875 x 250) ÷ (0.0821 x 400)

=6.66108
