If  0.5  mole  of  BaCl₂  is  mixed  with  0.20  mole  of Na₃PO₄,  the  maximum  number  of  moles  of Ba₃(PO₄)₂ then can be formed is

A.0.1✓ Correct
B.0.2
C.0.5
D.0.7
Explanation

2 3 4 3 4 2 3 2 ( ) 6 BaCl Na PO Ba PO NaCl → The coefficient of the balanced equation tells that 3 moles of 2 BaCl  react with 2 moles of 3 4 Na PO Required ratio of 2 3 4 3 2 BaCl Na PO 0.5 mole of 2 BaCl requires 0.333 mole of 3 4 Na PO But only 0.20 moles of 3 4 Na PO is given. Thus, 3 4 Na PO  is limiting reagent and 2 BaCl is in excess 3 4 2Na PO   (Limiting  reagent)  gives  1mole  of 3 4 2 ( ) Ba PO Therefore, 0.2 mol gives= 0.1 mole.
