We have been learning about the mole………..we know about Avogadro’s number (note that I spelt it right !! LOL) and the number of molecules in a mole. We also know how to work out the mass of one mole of substance. Guy-Lussac taught us that gases will carry out reactions in fixed, whole number ratios. This is equivalent to the numbers we use to balance an equation to show the mole ratio of the reactants and products.

So……I’ve got a question for you………… how much space does one mole of gas take up , at standard laboratory temperature and pressure?????? First in gets an award.
