A closed cylinder has a freely moving piston separating chamber 1 (56 mg of N $_{2}$ , molar mass 28) from chamber 2 (20 mg of helium, molar mass 4). Find the ratio $\frac{L _{1}}{L _{2}}$ of the chamber lengths at equilibrium.

Answer:

0.40

Solution:

Equal $P$ and $T$ give $V \propto n$ , so $\frac{L _{1}}{L _{2}} = \frac{n _{1}}{n _{2}} = \frac{\frac{56}{28}}{\frac{20}{4}} = \frac{2}{5} = 0.40$ .
