From the information given, the hydrogen gas was cooled from a temperature of 150 °C to 50 °C. The final volume of the gas after being cooled came to 75ml. To find out its original volume, we need to apply Charles law which is expressed as : V1 /T1 = V2 /T2 Where V1 is original volume Where T1 is original temperature Where V2 is the final volume Where T2 is the final temperature. We need V1 so V1 = (V2 × T1) ÷ T2 V1 = (75 × 150) ÷ 50 V1 = 225 ml Original volume of the gas was 225 ml
