A gas cylinder is filled with 4.00 moles of oxygen gas at 300.0 k. the piston is compressed to yield a pressure of 400.0 kpa. what is the volume inside the cylinder? a 3.19 dm3 b 6.25 dm3 c 24.9 dm3 d 31.5 dm3 c
we can use the ideal gas law equation to find the volume of the gas. PV = nRT P - pressure - 400 kPa V - volume n - number of moles - 4.00 mol R - universal gas constant - 8.314 Jmol⁻¹K⁻¹ T - temperature - 300.0 K substituting these values in the equation 400 000 Pa x V = 4.00 mol x 8.314 Jmol⁻¹K⁻¹ x 300.0 K V = 24.9 dm³ Volume is 24.9 dm³
