Answer to Question #314512 in Chemistry for sael

Question

Under what pressure a gas must be compressed in order to fit into a 4.00 ft3 tank if it occupies 300.0 ft3 at standard pressure?

Answer 1

From ideal gas law, and assuming temperature is kept constant, V₁P₁=V₂P₂ where V₁ and V₂ are volume before and after compression respectively, and P₁ and P₂ are pressure before and after compression respectively. Then P₂=P₁V₁/V₂=1atm*300ft³/4ft³=75atm.
