Question

An evaporating dish with a sample of a solution has a mass of 145.3 g. After evaporation, the dish and residue have a mass of 65.2 g. What additional information would be measured in the lab to calculate mass of the solute in the solution?
A) The mass of the solute
B) The mass of the solvent
C) The mass of the evaporating dish
D) The mass of the residue in the dish​

Answer 1

Answer: C

Explanation:

The extra information that should be measured is the mass of the evaporating dish so that you could calculate the mass of solute and solution and then percent by mass of the solute in solution.

So correct option is C the mass of the evaporating dish.
