Density of solid$=2.155\frac{g}{mL}$
We can find the mass of the benzene as mass of benzene$=58.8-25=33.8 g$ Volume of benzene$=\frac{mass}{density}=\frac{33.8g}{0.880\frac{g}{cm^3}}=38.4 mL$ (we know that 1cm^3=1 mL) Now volume of solid$=50-38.4=11.6mL$ Density of solid$=\frac{mass}{volume}$ we plug int the known values to obtain: Density of solid$=\frac{25}{11.6}=2.155\frac{g}{mL}$
