1

Stoichiometry

The ratio of the amount, in moles of each substance
Used to find quantities of reactants required to prepare required quantities of a product

2

How to calculate masses from equations and stoichiometry

Calculate the moles of the known mass
Mole ratio and convert back
Can involve volumes and concentrations

3

How to calculate percentage yield

Percentage yield=actual yield/ theoretical yield x100
Can do it with both moles or mass

4

Limiting reagent

Reactant that is not in excess that will be completely used up and stop the reaction

5

How to calculate the which reactant is the limiting one

Use mole ratio

6

Atom economy

Measure of how well atoms have been utilised
Important for sustainability as they make best use of natural resources

7

Atom economy equation

Sum of molar mass of desired products/ sum of molar masses of all products x100= atom economy
