230. mL 63.3 mL 46.5 mL 276.5 mL 183.5 mL A 230.0-mL sample of a 0.275 M solution is left on a hot plate overnight; the following morning the solution is 1.36 M. What volume of solvent has evaporated from the 0.275 M solution?
230. mL 63.3 mL 46.5 mL 276.5 mL 183.5 mL 230. mL 63.3 mL 46.5 mL 276.5 mL 183.5 mL 230. mL

Explanation / Answer

Moles of solution = .275*230*10^-3 = .06325

In morning,

1.36 = .06325/volume

voume = .0465 L

46.5 mL

Evaporated = 230-46.5 = 183.5mL
