Solution Concentration — Definition & Overview

A $NaCl$ solution is $5$% $NaCl$ by mass. That is to say, every $100$ grams of solution contains $5$ grams of $NaCl$. What is the molarity of the solution? Assume that the density of the solution is $1\text{ }\frac{g}{mL}$. The molar mass of $NaCl$ is $58.44\text{ } \frac{g}{mol}$.
