Answer:
4 moles of H₃PO₄
Explanation:
The reaction expression is given as;

Number of moles of water = 12moles
Unknown:
Number of moles of H₃PO₄ = ?
Solution:
From the balanced reaction expression we see that;
3 moles of water is produced from 1 mole of H₃PO₄
So; 12 moles of water would be produced from = 4 moles of H₃PO₄
