Gay Lussac's Law states that the ratio of the volumes of gases with the same temperature and pressure is equal to the ratio of their molecular weights. This means that the ratio of the volumes of gases with the same temperature and pressure is equal to the ratio of the number of moles of gas present.
For example, consider two gases, oxygen (O2) and hydrogen (H2), both at standard temperature and pressure. According to Gay Lussac's Law, the ratio of their volumes would be equal to the ratio of their molecular weights. This means that 1 liter of oxygen would occupy the same volume as 1 liter of hydrogen.
The law can also be applied to calculate the volume of a gas given the volume of its sample and the temperature and pressure. Similarly, it can be used to calculate the number of moles of gas present in a given volume or mass
