Sodium reacts with chlorine.

2Na+Cl2→2NaCl2\text{Na} + \text{Cl}_2 \rightarrow 2\text{NaCl}2Na+Cl2​→2NaCl

Relative atomic masses (ArA_rAr​): Na=23\text{Na} = 23Na=23, Cl=35.5\text{Cl} = 35.5Cl=35.5

4.6 g of sodium is reacted with 3.55 g of chlorine. What is the maximum mass of sodium chloride that can be produced?
