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.
To determine the volume of solvent that has evaporated from the 0.275 molarity solution, we can use the formula:
M1V1 = M2V2
where:
M1 = initial molarity
V1 = initial volume
M2 = final molarity
V2 = final volume
We are given:
M1 = 0.275 molarity
V1 = 230.0 mL
M2 = 1.5 molarity
Now we can rearrange the formula to solve for V2:
V2 = (M1V1) / M2
Substituting the values we have:
V2 = (0.275 * 230.0) / 1.5
V2 = 42.33 mL
Therefore, 42.33 mL of solvent has evaporated from the 0.275 molarity solution.
