Answer:
1) P4O10 + 6H20 → 4H3PO4
2) 1.25 moles of P4O10
3) 7.5 moles of water
Explanation:
1. Write the balanced equation for this reaction
P4O10 + 6H20 → 4H3PO4
2) Determine the number of moles of P4O10 required to produce 5.00 moles of phosphoric acid.
For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4
If we get 5.00 moles of H3PO4, we'll have 5/4 = 1.25 moles of P4O10 consumed.
3) Determine the number of moles of water required to produce 5.00 moles of phosphoric acid
For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4
If we have 5.00 moles of H3PO4, we'll get (6/4)*5 = 7.5 moles of water consumed.
