Question

A 9.35g sample of a solid was placed in a 15.00mL flask. The remaining volume was filled with Benzene in which the solid is insoluble. The solid and Benzene together weigh 17.33 g. The density of Benzene is 0.876 g/mL. What is the density of the solid?

Answer 1

The problem ask to calculate the density of the solid if it has a mass of 9.35g and is place in a 15ml flask. Base on my calculation and further formulation about the density of the two, by subtracting the density of the Benzene, the solid has a density of 1.59g/ml. I hope this would help 

Answer 2

Answer: 1.58 g/ml

Explanation:

Given :Total mass= 17.33 g

Mas of solid = 9.35 g

Thus Mass of benzene = Total mass - Mass of solid= (17.33-9.35)g= 7.98 g

Density of benzene = 0.876 g/ml

Therefore Volume of benzene =
`\frac{\text {mass of benzene}}{\text {density of benzene}}=(7.98g)/(0.876g/ml)= 9.1 ml`

Total volume = 15 ml

Volume of solid = Total volume - Volume of benzene= (15-9.1)=5.9ml

Thus Density of solid=
`\frac{\text {mass of solid}}{\text {volume of solid}}=(9.35g)/(5.9ml)= 1.58g/ml`
