Calculations involving sucrose, molality, molarity, weight, mole fraction
A sucrose solution containing 30gram sucrose (C 12 H 22 O 11 ) in 300ml of that solution, the density of the solution is 2.04g/mm. when these are provided: C=12, H=1, O=16, calculate: (i) Molality of sucrose solution (ii) Molarity of sucrose solution (iii) Weight of sucrose solution (iv) Mole fraction of sucrose solution To answer question (i) and (ii) we should know what is molality and molarity to avoid confusion that may arise. Molality is a measure of the concentration of a solute in a solution in terms of amount of substance in specified amount of mass of the solvent. It is also known as molal concentration. Its ...
