You need to quote the density of the solution...

#### Explanation:

We got the quotient...$\text{molarity"="moles of solute"/"volume of solution}$...

We want the quotient...

"mass of solute"/"mass of solute + mass of solvent"xx100%

And thus a quotation of solution density is required to address the denominator....
