i have no idea how to set this problem up! please help!

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?

  • Chemistry -

    total 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
