(chemistry only) (HT only) State that one mole of any gas at room temperature and pressure occupies 24 dm3.

In the subtopic Gas volumes and amount of substance, this learning objective focuses on (chemistry only) (HT only) State that one mole of any gas at room temperature and pressure occupies 24 dm3. It sits within Use of amount of substance in relation to volumes of gases (chemistry only) (HT only) for AQA GCSE Chemistry 8462 Unit 4.3, so the explanation must stay anchored to quantitative chemistry rather than drifting into a general chemistry idea. Approved keywords to use include chemistry only, HT only, mole, room temperature and pressure, 24 dm3. Room temperature and pressure (RTP). means standard conditions for gas measurements, typically defined as 20-25°C and 1 atmosphere pressure Avoid the mistake of students often confuse the volume occupied by one mole of gas at room temperature and pressure, thinking it is 22.4 dm3 instead of 24 dm3; instead, remember that at room temperature and pressure, one mole of any gas occupies 24 dm3, not 22.4 dm3. Use this value in calculations involving gas volumes For exam answers, always recall that one mole of any gas occupies 24 dm3 at room temperature and pressure when answering gas volume questions
