Question -
A solution is prepared by dissolving 10 grams of solute in 100 grams of water. Calculate the mass percentage of the solution.
Options:
A .  9.09%
B .  10%
C .  9.90%
D .  10.09%
Answer: Option A : A Mass percentage is used to measure the concentration of a solution. A solution contains solute and solvent. Mass percentage of a solution =Mass of the soluteMass of the solution×100 Given, mass of solute = 10g mass of solvent = 100 g The total amount of solution = 10 + 100 = 110g Mass percentage of a solution = 10110×100=9.09%
