Answer to Question #107409 in General Chemistry for Alyssa

Question

An aqueous solution in a glass beaker contains 2.65 mol of an unknown solute with a solubility of 60 g/100 g of water at the current temperature. All of the solute is completely dissolved and the solution is still unsaturated. If you are trying to determine the molarity of this unsaturated solution, what other piece(s) of information do you need? Choose ALL that are needed and ONLY what is needed! *

Answer 1

Molarity = mol of solute / L of solution

2.65 mol of solute is given

So the volume (V) of the solution is required!

C = n/V.

The desirable result will be also found if the mass / volume of water is given, as well as the molar mass of unknown substance :)
