A 22.19-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 50.0 mL. The solid and toluene together weigh 47.27 g. The density of toluene at the temperature of the experiment is 0.864 g/mL. What is the density of the solid?

**Steve**, Monday, August 20, 2012 at 10:03pmtotal mass: 47.27g

solid mass: 22.19g

so, toluene mass: 25.08g

toluene density is .864g/ml, so toluene volume: 25.08g / 0.864g/ml = 29.03ml

so, solid volume: 20.97ml

solid density: 22.19g/20.97ml = 1.058g/ml
