Question

A gas tank contains 3 gases (N2, O2, CO2). The total pressure of the gases is 825 mmHg. If the pressure of CO2 in 125 mmHg and the pressure of O2 is 350 mmHg, what is the partial pressure of N2 gas?

Answer 1

Answer:350 mmHg

Step-by-step explanation:

use Dalton’s law:

P Total = P gas 1 + P gas 2 + P gas 3

825= P1+ 350+ 125

350+125=475

825-475= 350

P1= 350 mmHg
