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

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.
