Question

How many moles of NaCl could be made by combining 20,000 moles of Na with 2 moles of CI?

Answer 1

Answer:

None of the above.

Explanation:

The limiting factor of this  is the chlorine. You only have 2 moles of chlorine.

2Na + Cl_2 ==> 2*NaCl

The equation tells you that for every mol of Cl2 that you have, you require 2 moles of Na and you get 2 moles of NaCl

So what that means is that if you have 2 mols of Cl2, you need just 4 moles of Na, and you will get 4 mols of NaCl

Since 4 is not one of your choices, the answer is none of the above
