Answer:
3 moles of 
is needed for 
to be fully consumed.
Explanation:
For the balanced equation:
⇒ 
First, find the moles of Na corresponding to the 69g used the general definition of mol:
We observe that the equation is balanced and the stoichiometric ratio between them is 1: 1.
According to this, one mole of Na will react with one mole of Cl.
3 moles of is needed for to be fully consumed.
