Formula for percent yield in chemistry?

Percentage yield is worked out as (amount you got/ amount you could have got) x 100 You should do the calculation in moles so weigh your compound, work out its molar mass and divide the mass by the molar mass to get number of moles. Then you have to work out your maximum theoretical yield - work out how many moles of reactant you started with and check the stoichiometric ratio from your balanced equation to find how many moles you expected to get. In organic reactions a yield of 60% or so is normal. The more steps you went through in your preparation, the lower you would expect your yield to be. Many reactions just do give a low yield anyway, because they are at equilibrium rather than going to completion, like the Haber process.
