Mass percent is given by:
[tex]mass\%=\frac{mass\text{ }solute}{moass\text{ }of\text{ }solution}\times100[/tex]We will firstly use the desnity to calculate the mass of the solution:
[tex]\begin{gathered} \rho=\frac{mass}{volume} \\ \rho:density \\ 1.06\text{ }gmL^{-1}=\frac{mass}{875\text{ }mL} \\ \\ mass=875\text{ }mL\times1.06\text{ }gmL^{-1} \\ mass(solution)=927.5g \end{gathered}[/tex]Now that we have the mass of the solution we are able to calculate the mass percent:
[tex]\begin{gathered} mass\%=\frac{98.6g}{927.5g}\times100 \\ \\ mass\%=10.6\% \end{gathered}[/tex]Answer: Mass percent is 10.6%
