Question
If 0.5 mole of $BaCl_2$ is mixed with 0.20 mole of $Na_3PO_4$, the maximum number of moles of $Ba_3$($PO_4$)2 then can be formed is
💡 Solution & 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.
