The new volume of the gas is 16.3 L.

Boyle's law

Boyle's law states that the volume of a fixed mass of gas is inversely proportional to its pressure, at a constant temperature.

To calculate the new volume of the gas, we use the expression from Boyle's law.

Formula:

  • PV = P'V'............. Equation 1

Where:

  • P = initial pressure of gas
  • V = Initial volume of gas
  • P' = Final pressure of gas
  • V' = Final volume of gas

Make V' the subject of the equation

  • V' = PV/P'............. Equation 2

From the question,

  • V = 20 L
  • P = 2.5 atm
  • P' = 3.1 atm

Substitute these values into equation 2

  • V' = (20×2.5)/3.1
  • V' = 16.13 L.

Hence, The new volume of the gas is 16.3 L.
