#### Answer

16.6 L

#### Work Step by Step

Mass percent= $\frac{\text{mass of the solute}}{\text{mass of the solution}}\times100\%$
$\implies \frac{2.25\times10^{3}\,g}{\text{mass of the solution}}\times100\%=12.0\%$
$\implies \text{mass of the solution}=$
$\frac{2.25\times10^{3}\,g}{12.0}\times100=18750\,g$
Volume= $\frac{\text{mass}}{\text{density}}=\frac{18750\,g}{1.131\,g/mL}=16600\,mL$
$=16600\,mL\times\frac{1\,L}{1000\,mL}=16.6\,L$
