A flask contains a gas mixture of hydrogen and nitrogen. The total pressure of the mix is 2.0 atm. The partial pressure of the hydrogen is 0.8 atm. What is the partial pressure of the nitrogen?

Answer:

[tex]P_{N_2}=1.2atm[/tex]

Explanation:

Hello,

In this case, considering the Dalton's law states that the total pressure of a system equals to the summation of all the pressures of the gases in the system as shown below:

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

In such a way, for the given system, we've got:

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

Finally, solving for the partial pressure of nitrogen, we obtain:

[tex]P_{N_2}=P_T-P_{H_2}=2.0atm-0.8atm=1.2atm[/tex]

Best regards.
