Phosphorus can be prepared from calcium phosphate by the following reaction:
Phosphorite is a mineral that contains 
plus other non-phosphorus-containing compounds. What is the maximum amount of 
that can be produced from 2.3 kg of phosphorite if the phorphorite sample is 75% by mass? Assume an excess of the other reactants.
Answer: Thus the maximum amount of that can be produced is 0.345 kg
Explanation:
Given mass of phosphorite = 2.3 kg
As given percentage of phosphorite is = 
According to stoichiometry:
2 moles of phosphorite gives = 1 mole of
Thus 5.56 moles of phosphorite give= 
of
Mass of 
Thus the maximum amount of that can be produced is 0.345 kg
