Volume and pressure equivalence

Chemistry Level 2

A balloon is inflated with helium gas at room temperature of \(25^\circ C\) and at \(1bar\) pressure when its initial volume is \(3.0\text{ L}\) and allowed to rise in air. As it rises in air external pressure decreases and volume of gas increases till finally it bursts when external pressure is \(0.3bar\).What is the limit to which volume of the balloon can be inflated?

Given :
\(Pressure(1)=1bar\) , \(Volume(1)=3.0L\)

\(Pressure(2)=0.3bar\) ,\(Volume(2)=?\)
