a 230.0ml sample of a 0.275 molarity solution is left on a hot plate over night the folowing morning the solution is 1.5 molarity. what volume of solvent has evaportated from the 0.275 molarity solution?

initial mols = 0.230 x 0.275 = ?
Final mols = same = ?
M = 1.5 = ?mol/L
Solve for L and subtract from 0.230 to find amount evaporated.
