# If the total atmospheric pressure of a planet was 890 mmHg and the gases in the atmosphere were 10% oxygen, 80% nitrogen, 9.5% carbon dioxide, and .5% other gases, what is the partial pressure of each gas?

Jun 23, 2016

The total pressure is the sum of the individual partial pressures.

#### Explanation:

And thus ${p}_{\text{carbon dioxide}}$ $=$ 890*mm*Hgxx9.5%;

${p}_{\text{dioxygen}}$ $=$ 890*mm*Hgxx10%

${p}_{\text{dinitrogen}}$ $=$ 890*mm*Hgxx80%

${p}_{\text{carbon dioxide}}$ $=$ 890*mm*Hgxx9.5%

${p}_{\text{other gases}}$ $=$ 890*mm*Hgxx0.5%
