A230.-ml sample of a 0.240 m solution is left on a hot plate overnight; the following morning, the solution is 1.75 m. what volume of water evaporated from the 0.24 m solution?

The volume of water evaporated is 199mL

Explanation:

Concentration is calculated with the following formula

where n is the number of moles of solute and V is the volume of the solution (in this case is the same as the solvent volume) in liters.

So we isolate the variable n to know the amount of moles, using the volume given in liters

Now, we isolate the variable V to know the new volume with the new concentration given.

Finally, the volume of water evaporated is the difference between initial and final volume.
