Chemistry - Ideal Gas Question with Solution | TestHub

According to Dalton’s law,
Partial pressure of a component$=$Mole fraction$\times$Total pressure
As mass of${\mathrm{N}}_2=56\mathrm{g}$
Mass of${\mathrm{O}}_2=96\mathrm{g}$
Total pressure$=$10 atm
${\mathrm{n}}_{{\mathrm{N}}_2}=\frac{56}{28}=2,{\mathrm{n}}_{{\mathrm{O}}_2}=\frac{96}{32}=3$
${\mathrm{x}}_{{\mathrm{N}}_2}=\frac{2}{2+3}=0.4$
${\mathrm{x}}_{{\mathrm{O}}_2}=\frac{3}{2+3}=0.6$
${\mathrm{p}}_{{\mathrm{N}}_2}=0.4\times 10=4\mathrm{a}\mathrm{t}\mathrm{m}$
${\mathrm{p}}_{{\mathrm{O}}_2}=0.6\times 10=6\mathrm{a}\mathrm{t}\mathrm{m}$
