Mole-Concept and Stoichometry

19 Aug 2008 -
What you need to know for the topic on the Mole-Concept, formulae and stoichiometry
http://www.fileden.com/files/2008/6/10/1953044/mole%20concept.pdf

what you should know
- define relative atomic mass, Ar
- define relative molecular mass, Mr and calculate relative molecular mass
- calculate the percentage mass of an element in a compound when given appropriate information
- calculate empirical and molecular formulae from relevant data
- calculate stoichiometric reacting masses and volumes of gases (one mole occupies24 dm3)
- apply the concept of solution concentration (in mol/dm3 or g/dm3)
- calculate the %yield and % purity

Additionally there are summarised notes important for the particular topic on
SETS.

The notes on functions are summarized as shown in the following table in
preparation for the O Level Mathematics D.
