Aqueous hydrochloric acid $(HCl)$ will react with solid sodium hydroxide $(NaOH)$ to produce aqueous sodium chloride $(NaCl)$ and liquid water $(H_{2}O).$

Suppose $31.g$ of hydrochloric acid is mixed with $12\mathrm{.}4g$ of sodium hydroxide. Calculate the maximum mass of sodium chloride that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.
