1.

Calculate the number of moles of Ba3(PO4)2 that can be formed if 0.5 mole of BaCl2 is mixed with 0.2 mole of Na3PO4.​

Answer»

Explanation:

The answer is (d) 0.10 mole. Stoichiometrically, 2 moles of Na3PO4 can react with 3 moles of BaCl2 to FORM 1 mole of Ba3(PO4)2. THEREFORE, 0.2 mole of Na3PO4 can only react with 0.3 mole of BaCl2 to form 0.1 mole of Ba3(PO4)2
