what is a limiting reactant
- when a reaaction stops its because a reactant is used up
- the reactant that is used up is called the limiting reactant
- the amount of product formed = the amount of limiting reactant
the amount of product depends on the limiting reactant
- you can calculate the mass of a product by using the mass of limiting reactant and the equation
1) write out balanced equation
2) work out formula masses of reactants and products
3) find how many moles there are of the substance you know the mass of
4) work out how many moles there will be of the other substance
5) use number of moles to calculate the mass
