Answer : The partial pressure of \(N_2\) is, 66 Kpa
Solution :
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.
\(P_T=p_{N_2}+p_{O_2}+p_{H_2}\)
where,
\(P_T\) = total partial pressure = 282 Kpa
\(P_{N_2}\) = partial pressure of nitrogen = ?
\(P_{O_2}\) = partial pressure of oxygen = 110 Kpa
\(P_{H_2}\) = partial pressure of hydrogen = 106 Kpa
Now put all the given values is expression, we get the partial pressure of the nitrogen gas.
\(282Kpa=p_{N_2}+110Kpa+106Kpa\)
\(p_{N_2}=66Kpa\)
Therefore, the partial pressure of \(N_2\) is, 66 Kpa
