Moles equations

For solids   moles=mass/Mr

For Liquids   moles=volume/1000 * conc.

For gases   pV=nRT where n=moles

Titrations  

Will probably need to know the practical

Take average titre, use 2nd moles equation (for liquids), 1:1 ratio, find moles.

Moles in solution

Might need to know how to construct half equations to fine to reaction…
