Question

An ideal gas at $650$ Torr occupies a bulb of unknown volume. A certain amount of gas is withdrawn and found to occupy ${1.52cm}^3$ at one atmp. The pressure of the gas remaining in the $600$ torr. Calculate the volume of the bulb taking temperature constant.

Answer 1

Let the volume of bulb be $V$ $c{m}^3$.

After removing certain amount of gas, presence in the bulb is $600$ $torr.$

Using, $P_1{V}_1=P_2{V}_2$

$600\times V=760\times 1.56$

$V=1.976$ $c{m}^3$
