ollegr [7]

Answer:

P_{N_2}=1.0atm

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:

P_T=\Sigma P_i

For the given system:

P_T=P_{H_2}+P_{N_2}+P_{CH_4}

Solving for the partial pressure of nitrogen we obtain:

P_{N_2}=3.0atm-0.5atm-1.5atm=1.0atm

Best regards.
