How do you work out the %element ?
%element= Ar x number of atoms in the compound ÷ Mr of the compound x100
1 of 5
Calculating % yield
%yield= Actual mass of product during experiment ÷ theoretical mass of product from calculation x100
2 of 5
Number of moles
Mass(g) ÷ Ar/Mr
3 of 5
Coverting moles into mass of substance
Number of moles x (Ar or Mr) of element/compound
