Question

A liquid solvent is added to a flask containing an insoluble solid. The total volume of the solid and liquid together is 80.0 mL. The liquid solvent has a mass of 21.0 g and a density of 0.865 g/mL. Determine the mass of the solid given its density is 2.00 g/mL.

Answer 1

Answer:

Liquid: 38.7 g x 1 ml/0.865 g = ml of liquid

Vol of solid = 80.0 ml - ml of liquid

mass of solid = vol of solid x 2.75 g/ml

(100. g)
