A mixture of gases at $760$ torr contains $55.0 %$ nitrogen, $25.0 %$ oxygen and $20.0 %$ carbon dioxide by volume. What is the partial pressure of each gas in torr?

Solution

We know,
$P_{g a s} = n \times P_{t o t a l}$
Now,
$P_{N_{2}} = \frac{55}{100} \times 760 = 418 t o r r$
$P_{O_{2}} = \frac{25}{100} \times 760 = 190 t o r r$
$P_{C O_{2}} = \frac{20}{100} \times 760 = 152 t o r r$
