The volume of this same sample of gas if it were measured at STP is 386.09mL

HOW TO CALCULATE VOLUME:

The new volume of a gas sample can be calculated using the following expression:

P1V1/T1 = P2V2/T2

Where;

  • P1 = initial pressure
  • P2 = final pressure
  • V1 = initial volume
  • V2 = final volume
  • T1 = initial temperature
  • T2 = final temperature

According to this question, a sample of a certain gas has a volume of 452 mL at 711 mmHg and 26°C (299K).

(711 × 452)/299 = 760 × V2/273

1074.82 = 2.78V2

V2 = 1074.82 ÷ 2.78

V2 = 386.09mL

Therefore, the volume of this same sample of gas if it were measured at STP is 386.09mL.
