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

  • A 120 cm3
  • B 200 cm3
  • C 450 cm3
  • D 750 cm3

The correct answer is B. 200 cm3

From P1V1 = P2V2

1 * V1 = 1.5 * V2

((1 * 300)/1.5) = V2

∴ V2 = 200 cm3
