How many moles of nacl could be made by combining 20,000 moles of na with 2 moles of ci? a 20,000 moles naci 2 moles naci b. 1 mole nacl none of the above select the best answer from the choices provided a b c d

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

the answer would be b i believe
