How do you calculate moles of gas?
- volume = 0.5 × 24 = 12 dm 3
- Remember that 1 dm 3 = 1 000 cm 3 so the volume is also 12 000 cm 3
- The equation can be rearranged to find the number of moles if the volume of gas at rtp is known:
- number of moles = volume of gas at rtp ÷ 24.

How do you convert moles to liters at STP?
Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of 1 mole = 22.4 L is the basis for the conversion factor.
How do you calculate moles to liters?
Converting from moles to volume (liters): Multiply your mole value by the molar volume constant 22.4L. Converting from particles (atoms molecules or formula units) to moles: Divide your particle value by Avogadro’s number 6.02×1023. Remember to use parentheses on your calculator!
