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.
