A flask contains a gas mixture of hydrogen, nitrogen and methane. The total pressure of the mix is 3.0 atm. The partial pressure of the hydrogen is 0.5 atm, and the partial pressure of the methane is 1.5 atm. What is the partial pressure of the nitrogen?

Answer:

[tex]P_{N_2}=1.0atm[/tex]

Explanation:

Hello,

Considering the Dalton's law which states that the total pressure of a gaseous system is defined by the summation of the the partial pressures of the present gases:

[tex]P_T=\Sigma P_i[/tex]

For the given system:

[tex]P_T=P_{H_2}+P_{N_2}+P_{CH_4}[/tex]

Solving for the partial pressure of nitrogen we obtain:

[tex]P_{N_2}=3.0atm-0.5atm-1.5atm=1.0atm[/tex]

Best regards.
