Answer:

52.2g of KCl would be left

The mass of KCl will remain despite the solution is been heated

Explanation:

When you are heating a solution, just the solvent (In this case, water), will be evaporated and, in theory, the mass of KCl will remain despite the solution is been heated.

Now, the mass of KCl that you can obtain from 350mL of a 2.0M solution will be:

<em>Moles KCl:</em>

350mL = 0.350L * (2.0mol / L) = 0.700 moles

<em>Mass KCl -Molar mass: 74.55g/mol-:</em>

0.700mol * (74.55g/mol) = 52.2g of KCl would be left
