The number of moles of copper, phosphorous and oxygen present in the 5 moles of Cu₃(PO₄)₂ are 15, 20 and 40 respectively.
<h3>What is stoichiometry?</h3>
Stoichiometry of any chemical equation gives idea about the amount of species present before and after the reaction.
Dissociation reaction of Cu₃(PO₄)₂ is shown as below:
Cu₃(PO₄)₂ → 3Cu²⁺ + 2PO₄³⁻
From the stoichiometry of the equation, it is clear that:
1 mole of Cu₃(PO₄)₂ produces 3 moles of copper atom, 2 moles of phosphorous atoms an 8 moles of oxygen atom.
5 moles of Cu₃(PO₄)₂ = produces 3×5=15 moles of Cu
5 moles of Cu₃(PO₄)₂ = produces 2×5=10 moles of P
5 moles of Cu₃(PO₄)₂ = produces 8×5=40 moles of O
Hence required moles of copper, phosphorous and oxygen are 15, 20 and 40 respectively.
