1. calculate the weight of the benzene by subtracting the total weight minus the weight of the sample (17.33-9.35= 7.98 g) this is the mass of benzene
2. Then density= m/v, you can calculate the volume of benzene "v= mass/density"
v= 7.98/0.876mL = 9.195mL
3. Subtract the volume of the benzene from the total volume to calculate the volume of the solid. 15.00-9.195= 5.805 mL
4. with the volume and the mass of the solid sample you can calculate the density of the solid.
