Question

In a mixture of gases the partial pressure of nitrogen is 0.79 atm, the partial pressure of oxygen is 0.20 atm, and the partial pressure of hydrogen is 0.00444 atm. What is the total pressure of the mixture of gases?

Answer 1

The total pressure of the gas mixture is the sum of the partial pressures of its components.

$P=P_1+P_2+...+P_n$

$P=0.79atm+0.2atm+0.00444atm$ $=0.99444 atm$
