Question

A mixture of gases contains 5.77 moles of oxygen (O₂), 0.94 moles of hydrogen (H₂), and 9.19 moles of nitrogen (N₂). Calculate the partial pressures of the gases if the total pressure is 4.00 atm at a certain temperature.

Answer 1

$5.77+0.94+9.19=15.9$

$P_{O_2}=\frac{5.77}{15.9}×4.00=1.45$

$P_{H_2}=\frac{0.94}{15.9}×4.00=0.24$

$P_{N_2}=\frac{9.19}{15.9}×4.00=2.31$
