Chemistry Problem: Concentration of Solution After Evaporation

What happened upon heating in a chemistry experiment?

Upon heating, 517. ml of water was evaporated from 834. ml of 0.655 m C6H12O6(aq). What is the resulting concentration of this solution?

Answer:

The resulting concentration of the solution is 1.72 M.

To find the resulting concentration, we need to calculate the number of moles of C6H12O6 before and after the evaporation. The resulting concentration of the solution is 1.72 M.

Explanation:

To find the resulting concentration, we need to calculate the number of moles of C6H12O6 before and after the evaporation. First, let's find the number of moles of C6H12O6 in the original solution using the formula:

Moles = concentration x volume

Moles = 0.655 M x 0.834 L

= 0.545 mol

Since the volume reduces to 0.317 L after evaporation, the resulting concentration would be:

Concentration = Moles / Volume

Concentration = 0.545 mol / 0.317 L

= 1.72 M

Therefore, the resulting concentration of the solution is 1.72 M.
