Number of moles
Mass / Mr
Percentage yield
(Actual mass of product/ Maximum theoretical mass of product) x 100
Percentage atom economy
(Mr of desired product/total Mr of total reactants) x 100
concentration (g/dm^3)
mass of solute/volume of solution (dm^3)
concentration (mol/dm^3)
number of moles / volume of solution (dm^3)
cm^3 to dm^3
divide by 1000
number of moles of gas
Volume of gas (dm^3) / 24dm^3
conversion between g/dm^3 and mol/dm^3
Concentration in g/dm^3 = concentration in mol/dm^3 x Mr
Atom economy
Mr of desired product/Mr of all reactants x100
