Question

A vessel has 6 g of oxygen at pressure P and temperature 400 K . A small hole is made in it so that oxygen leaks out. How much oxygen leaks out if the final pressure is $\mathrm{P} / 2$ and temperature 300 K\

Professor PC Thomas Classes · Answer

$\mathrm{PV}=x \mathrm{kT}$ where $x=$ the number of grams Case I:- $\mathrm{PV}=6 \mathrm{~K} 	imes 400$\ Case II:- ${ }^{\frac{\mathrm{P}}{2}} 	imes \mathrm{V}=x \mathrm{~K} 300$\ Divide $2=\frac{6 	imes 400}{\mathrm{x} 	imes 300}$\ $	herefore x=$ gram\
