# Calculate the mass percent of a solution that is prepared by adding {eq}62.3 \, \mathrm{g} {/eq} of {eq}\mathrm{NaOH} {/eq} to {eq}343 \, \mathrm{g} {/eq} of {eq}\mathrm{H_2O} {/eq}.

## Question:

Calculate the mass percent of a solution that is prepared by adding {eq}62.3 \, \mathrm{g} {/eq} of {eq}\mathrm{NaOH} {/eq} to {eq}343 \, \mathrm{g} {/eq} of {eq}\mathrm{H_2O} {/eq}.

## Mass Percent of a solution:

The concentration of a solute expressed in terms of percentage of solute in a given mass of the solution. Mathematically, it is calculated as follows:

{eq}\textrm{Mass Percent}(m/m)= \frac{\textrm{mass of solute}}{\textrm{mass of solution}}\times 100 {/eq}
