Molar gas volume
What is Molar gas volume?
The molar gas volume is the volume occupied by one mole of any gas under stated conditions; for Cambridge IGCSE Chemistry 0620 it is taken as 24 cubic decimetres per mole at room temperature and pressure, equivalently 24 000 cubic centimetres per mole.
This definition is part of the Stoichiometry chapter in Cambridge IGCSE Chemistry.
Common mistakes with Molar gas volume
- "Multiply the mass by 24." Fix The molar gas volume multiplies an amount, not a mass. Convert with \(n = m/M\) first, then multiply.
