Answer:
653.1 g of H₃PO₄ will be produced, by 10 moles of H₂O
Step-by-step explanation:
P₄O₁₀ + 6H₂O → 4H₃PO₄
1 mol of phosphorus oxide reacts with 6 mol of water to produce 4 mol of orthophosphoric acid.
If 6 moles of water make 4 mol of acid
10 mol water, will make (10 .4)/ 6 = 6.67 moles of acid
Molar mass H₃PO₄ = 97.97 g/m
Mol . molar mass = mass → 6.67 moles . 97.97 g/m = 653.1 g
