An LPG (Liquified Petroleum Gas) cylinder weighs 15.0 kg when empty. When full, it weighs 30.0 kg and shows a pressure of 3.0 atm . In the course of usage at 27^{\circ} {\C}, the mass of the full cylinder is reduced to 24 \cdot 2 {\kg}. The volume of the used gas in cubic metre at the normal usage condition ( atm and 27^{\circ} {\C} ) is (assume LPG to be normal butane and it behaves ideally)

An LPG (Liquified Petroleum Gas) cylinder weighs 15.0 kg when empty. When full, it weighs 30.0 kg and shows a pressure of 3.0 atm . In the course of usage at 27∘C, the mass of the full cylinder is reduced to 24⋅2‌kg. The volume of the used gas in cubic metre at the normal usage condition ( atm and 27∘C ) is (assume LPG to be normal butane and it behaves ideally)
