Question

How many mols of H3PO4 are produced when 284 g P4O10 reacts completely to form H3PO4? P4O10 + 6H2O --> 4H3PO4

Answer 1

Answer:

4 moles of H3PO4

Explanation:

Molar mass of P4O10 = 284 g/mol

Number of moles of P4O10  reacted = 284g/284 g/mol = 1 mole of P4O10

From the reeaction equation;

1 mole of P4O10 yields 4 moles of H3PO4

Hence, 284 g of P4O10 yields 4 moles of H3PO4
