Correct Answer: 53

Solution and Explanation

Reaction of BaCl2 and Na3PO4

Given Reaction:

The reaction between BaCl2 and Na3PO4 is:

3BaCl2 + 2Na3PO4 → Ba3(PO4)2 + 6NaCl

Given Moles:

  • Barium chloride (BaCl2): 5 moles
  • Sodium phosphate (Na3PO4): 3 moles

Calculation:

The balanced equation shows that 3 moles of BaCl2 react with 2 moles of Na3PO4 to produce 1 mole of Ba3(PO4)2.

Now, using the mole ratio from the equation:

  • From 3 moles of BaCl2, 1 mole of Ba3(PO4)2 is formed.
  • So, from 5 moles of BaCl2, the moles of Ba3(PO4)2 formed will be: 5 moles × (1 mole Ba3(PO4)2 / 3 moles BaCl2) = 5/3 = 5 moles.

Conclusion:

The number of moles of Ba3(PO4)2 formed is 5 moles.
