40% is 40 g sucrose/100 g solution.
Use density to convert 100 g solution to volume in cc and convert that to L.
Convert 40 g sucrose to mols. mol = grams/molar mass.
Then M = mols/L
At 25 °C, the density of a 40.0% (m/m) solution of sucrose, C12H22O11, in water is 1.18 g/mL. What is the molarity of this solution?
