Question 9 Which of the following would have the highest mass?
A
0.75 mol CO3(PO4)2
B
1.2 mol Fel2
С
10 mol CH3C1
D
17.5 mol Cl2

A. 3 mol  3 mol Al:

Explanation:

Te given balanced chemical equation is :

According to the stochiometry :

A: 3 mol  3 mol Al:

3 moles of chlorine reacts with 2 moles of aluminium

B. 2 mol  3 mol :

2 moles of aluminium  reacts with 3 moles of chlorine

C.  2 mol  2 mol Al

2 mol of aluminium produces 2 mol of  

D. 3 mol  2 mol  

3 moles of chlorine produces with 2 moles of  

Thus the conversion factor not used for mole to mole calculations is  3 mol  3 mol Al:
