1. Calculate the percentage economic element in the following ore minerals: % metal
moles metal x atomic weight of metal
sum (moles of each element x atomic weight of each element]
X 100
Molar masses (g/mol): Cu-63.55, Fe- 55.85, S-32.06, C- 12.01, 0- 16.00, H-1.008
a) Bornite- Cu5FeS4
b) Azurite- Cu3(CO3)2(OH)2
