In this episode, we discuss the amount of substances in relation to volumes and gas.

Under identical temperature and pressure, equal quantities of different gases, measured in moles, occupy the same volume.

Specifically, one mole of any gas occupies 24 dm³ at standard room temperature (20°C) and pressure (1 atm).

This principle allows for the calculation of gas volumes in chemical reactions using balanced equations and the known volume of one gaseous reactant or product.

Therefore, understanding the amount of substance (in moles) provides a direct link to predicting gas volumes in various chemical processes.
