Question

If 0.50 mole of BaCl2 is mixed with 0.20 mole of Na3PO4, the maximum number of moles of Ba(PO4)2 that can be formed is

Solution

Correct option is

0.10

 

The balanced chemical reaction is  

                   3BaCl2 + 2Na3PO4 âŸ¶ Ba3(PO4)2 + 6NaCl  

In this reaction, 3 moles of BaCl2 combines with 2 moles of Na3PO4. Hence, 0.5 mole of BaCl2 require  

                       

Since available Na3PO4 (0.2 mole) is less than required mole (0.33), it is the limiting reactant and would determine the amount of productBa3(PO4)2

∵ 2 moles of Na3PO4 gives 1 mole Ba3(PO4)2  

∴ 0.2 mole of Na3PO4 would give    

= 0.1 mole Ba3(PO4)2.
