I've learnt that m = n x M and n = m/M are formels that you can use when you want the mole mass, mass or the amount of substance. For example: Calculate the amount of substance for 750g propan. Propan= C3 H8 12x3 + 1,01x8 = 44,08 750/44,08 = 17,01 g/mol Also I understood the video very well!

1 (unit).mole of a compound Weighs the molecular weight of the compound, in (units). E.g. 1 gram.mole of Oxygen (molecular weight 32) is 32 grams. 1 gram.mole of any gas at Standard temperature and pressure (stp) occupies a volume of 22.4 litres. It will contain N (Avogadro's number) molecules 6022 x 10^20 This has been found to be physical fact Molecular weight is the combined weight of all the atoms in the molecule. Atomic weight is weight of the substance atom, compared to a Hydrogen atom. I.e. the density of the gas compared to density of Hydrogen. How many times heavier it is. Lack of the above knowledge is what leads to the Endless Boloney and confusion which this teacher so perfectly demonstrates.
