Question

How many grams of cao are required to neutralise 852g of p4o10 ?

Answer 1

Answer:

1008 g of CaO

Explanation:

Number of moles of P₄O₁₀ in 852 grams = 852/284 = 3 moles

The balanced chemical reaction is;

6 CaO + P₄O₁₀ -----------> 2 Ca₃(PO₄)₂

6 moles of CaO reacts with 1 mole of P₄O₁₀ to give 2 moles of Ca₃(PO₄)₂.

But there are 3 moles of P₄O₁₀ present in the sample.

So, 18 moles of CaO reacts with 3 moles of P₄O₁₀ to give 6 moles of Ca₃(PO₄)₂.

Mass of 18 moles of CaO = 18 x 56 = 1008 grams

Therefore 1008 grams of CaO is required to react with 852 grams of P₄O₁₀.
