A230.0-ml sample of a 0.275 m solution is left on a hot plate overnight; the following morning the solution is 1.15 m. what volume of solvent has evaporated from the 0.275 m solution?

The volume of solvent evaporated is 173.57 mL

Explanation:

   .....(1)

Molarity of solution = 0.275 M

Volume of solution = 230.0 mL

Putting values in equation 1, we get:

As, the moles of solution remains the same.

When solvent gets evaporated, the volume of the solution is calculated by using equation 1:

Moles of solution = 0.0632 moles

Molarity of the solution = 1.15 M

Putting values in equation 1, we get:

Volume of solution evaporated = (230.0 - 56.43) mL = 173.57 mL

Hence, the volume of solvent evaporated is 173.57 mL

the answer is the first option

explanation:

just googled it m8. not that hard

lol
