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 phosphorite sample is 75% by mass? Assume an excess of the other reactants.

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.

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

your answer would be a. 12.5 kg

it means there are 3 atoms of oxygen
