Answer:
6.2moles of Na are needed.
Explanation:
First, we need to generate a balanced equation for the reaction between sodium and chlorine to produce sodium chloride. This is illustrated below:
2Na + Cl2 —> 2NaCl
From the equation,
2moles of Na produced 2moles of NaCl.
Therefore Xmol of Na will produce 6.2moles of NaCl i.e
Xmol of NaCl = (2 x 6.2)/2 = 6.2moles
Therefore, 6.2moles of Na are needed to produce 6.2moles of NaCl
