23. Relative formula mass.

This tells you the number of times

a molecule is heavier than an

atom of hydrogen E.g. Work out the

Mr of CO2.

24.The recipe bit …What mass of ammonia is produced from 14g of nitrogen?

N2 + 3H2 2NH3 Underline

Molecules in

x relative formula mass

Same at both sides

Keep the same units!

25. Percentage yield

You expected 100 tonnes of ammonium sulphate but the actual mass was 25 tonnes.

What was the % yield?

Good luck!
