Question

Oxygen gas is 21 % of Earth’s atmosphere. If the atmospheric pressure is 439mmHg, what is the partial pressure of oxygen at that location?

Forgot the formula for partial pressure! Please help.

Answer 1

`92.19` mmHg

Explanation:

Since gaseous pressure is directly related to the number of gaseous moles, all we need to do is multiply the percentage (in decimal form) by the total atmospheric pressure:

`.21 * 439` mmHg = `92.19` mmHg
