Question- A 32.50-g sample of a solid is placed in a flask. Toluene, in which the solid is insoluble, is added to the flask so that the total volume of solid and liquid together is 46.00mL. The solid and toluene together weigh 58.72g. The density of toluene at the temperature of the experiment is 0.864 g/mL.

What is the density of the solid?

I am thankful to receive an expert help to solve the above problem
