Question

A solution contains 60g of sugar in 480g of water. Calculate the concentration of solution in terms of mass by mass percentage of the solution.

Answer 1

Answer: Mass percentage of solute = 11.1 % and mass percentage of solvent = 88.8%.

Explanation: Given: Mass of solute i.e. sugar = 60 g

Mass of solvent i.e. water = 480 g

mass of solution = Mass of solute+Mass of solvent= 60 g+480 g=540 g

${\text {mass by mass percentage of solute }}=\frac{\text {mass of solute}}{\text { mass of solution}}\times 100\%$

${\text { mass by mass percentage of solute}}=\frac{60g}{540g}\times 100\%=11.1\%$

${\text { mass by mass percentage of solvent}}=\frac{480g}{540g}\times 100\%=88.8\%$

Answer 2

Answer:

Mass percentage of solute = 11.1 % and mass percentage of solvent = 88.8%.

Explanation: Given: Mass of solute i.e. sugar = 60 g

Mass of solvent i.e. water = 480 g

mass of solution = Mass of solute+Mass of solvent= 60 g+480 g=540 g
