How do you calculate moles of gas?

Molar volume of gases
  1. volume = 0.5 × 24 = 12 dm 3
  2. Remember that 1 dm 3 = 1 000 cm 3 so the volume is also 12 000 cm 3
  3. The equation can be rearranged to find the number of moles if the volume of gas at rtp is known:
  4. number of moles = volume of gas at rtp ÷ 24.
