# A gaseous mixture was prepared by taking equal mole of $CO_{2}\ and\ N_{2}$ . If the total pressure of the mixture was found 1 atmosphere, the partial pressure of the nitrogen $\left ( N_{2} \right )$ in the mixture is: Option 1) 0.5 atm Option 2) 0.8 atm Option 3) 0.9 atm Option 4) 1 atm

P Plabita

Partial Pressure of a gas in gaseous mixture -

Partial Pressure = (Total Pressure of Mixture) $\times$ (mole fraction of gas)

-

$P_{N2}=\frac{Qn_{N2}}{n_{N2+n_{o2}}}.P=(\frac{1}{2}).1\:atm=\frac{1}{2}\:atm$

$P_{N2}=0.5\:atm$

Option 1)

0.5 atm

This solution is correct

Option 2)

0.8 atm

This solution is incorrect

Option 3)

0.9 atm

This solution is incorrect

Option 4)

1 atm

This solution is incorrect
