The gas laws can be summarised in the ideal gas equation. pV = nRT 0.960 g of oxygen gas is contained in a vessel of volume 7.00 × 10⁻³ m³ at a temperature of 30 °C. Assume that the gas behaves as an ideal gas. What is the pressure in the vessel?

A1.07 kPa

B2.14 kPa

C10.8 kPa

D21.6 kPa

✓ Correct answer

C: 10.8 kPa
