Molecular and Empirical Formulae

Do you know how to determine a compound’s empirical formula?

All calculations in this quiz are relevant to Edexcel Combined Science and Edexcel Chemistry.

AQA Trilogy and Chemistry students only need to know what empirical formulae are and do not need to complete this whole quiz.

OCR (all courses) and AQA Synergy students need to be able to determine an empirical formula from the number of atoms in a compound but do not need to understand the other calculations in this quiz. E.g. determining molecular formulae from empirical formulae and relative atomic mass.

Good Luck!
