More maths to master, I’m afraid 😕.
The good news is that in many ways, working with gases in Chemistry calculations is simplified because we know that the volume of space that a gas occupies depends on the temperature and pressure of that gas, not the number of molecules present (the molecules are so far apart from each other that their individual size or mass is irrelevant).
