alisha [4.7K]

Remark

The balance numbers in front of the chemicals tell you how to set up the proportion to solve your question

For every 2 moles Na only 1 mole of Cl2 is required.

Equation

2 moles Na:1 mole Cl2 :: x moles Na:4 moles Cl2

Solution

2/1 = x/4                 Cross multiply

2*4 = x*1

8 = x

Conclusion

8 moles of Na will be used. <<< Answer
