The ratio of the initial to final pressure of a given mass of gas is 1:1.5. Calculate the final volume of the gas if the initial volume was 300 cm3 at the same temperature
120 cm3
200 cm3
450 cm3
750 cm3
Maelezo
From P1V1 = P2V2
1 * V1 = 1.5 * V2
((1 * 300)/1.5) = V2
∴ V2 = 200 cm3
1 * V1 = 1.5 * V2
((1 * 300)/1.5) = V2
∴ V2 = 200 cm3
