Key terms
mole
A unit of measurement for amount of substance, representing 6.022 x 10^23 particles. In Gas volumes and amount of substance, this term helps explain (chemistry only) (HT only) State that equal amounts in moles of gases occupy the same volume under the same temperature and pressure conditions for AQA GCSE Chemistry 8462 Unit 4.3.
gas volume
The space occupied by a gas, typically measured in cubic decimeters (dm3) at specific temperature and pressure.
mole
A unit of measurement for amount of substance, defined as containing exactly 6.022 x 10^23 particles.
room temperature and pressure (RTP)
Standard conditions for gas measurements, typically defined as 20-25°C and 1 atmosphere pressure.
mole
