Term 1, week 9

This week I want you to concentrate on making sure you know how to:
  • calculate the emperical and molecular formula of a compound
  • calculate the % composition
  • use mole ratios to calculate the mass of substance formed or the mass used in an reaction.
In other words go over the stuff from VC on 23rd. I will be writing some questions essentially the same as those 3 problems for the A.std and I would like them completed this term. There are some extra problems inj the attachment if you want extra practice. You can fax the answers to me when you have finished them.
