The relationship between empirical formula and molecular formula. Students should be able to: calculate empirical formula from data giving composition by mass or percentage ...
The reformed AS and A-level specifications will have no direct assessment of practical work that contributes to the AS or A-level grades.
Revision for AQA Chemistry AS and A-Level from 2015, including summary notes, worksheets and past exam questions for each topic and paper.
Empirical & Molecular Formulae. The molecularformula is the formula that shows the number and type of each atom in a molecule. E.g. the molecular formula of ethanoic acid is C 2 H 4 O 2. The empiricalformula is the simplest whole number ratio of the elements present in one molecule or formula unit of the compound.
