Question

How many moles of Ba3(PO4)2 can be formed when 1.3 moles of BaCO3 react with 2.5 moles of FePO4?

3BaCO3 + 2FePO4 yields Ba3 (PO4)2+ Fe2 (CO3)3

2.6 mol Ba3(PO4)2
2.5 mol Ba3(PO4)2
1.3 mol Ba3(PO4)2
0.43 mol Ba3(PO4)2

Answer 1

3BaCO3 + 2FePO4 ----> Ba3(PO4)2+ Fe2(CO3)3
3 moles.................................. 1 mol

3 mol BaCO3 ---- 1 mol Ba3(PO4)2
1.3 mol BaCO3 ---- X mol Ba3(PO4)2
X = (1.3×1)/3 = 0.43 mol
