# How can I calculate the concentration of a solution in mass percent?

$\text{mass percent}$ = $\text{Mass of solute"/"mass of solution}$ x $\text{100%}$
$\text{mass percent}$ = $\text{Mass of solute"/"mass of solution}$ x $\text{100%}$
$\text{mass percent}$ = $\text{58.4 g NaCl"/"525 g of solution}$ x $\text{100%}$ = $\text{11.1%}$
