Hint: Both the solution prepared by Ramesh and Sarika are done by mass percentage formula. In this formula mass of the solute is divided by the total mass of solute and solvent multiplied with 100. This formula determines the concentration of the formula.
Complete answer:Given
Mass of solute (sugar) used by Ramesh is 10 g.
Mass of solvent (water) used by the Ramesh is 100 g.
Mass of solute (sugar) used by Sarika is 10 g.
Mass of solution prepared by Sarika is 100 g.
The formula for calculating the mass percentage is shown below.
So ,Solution formed by Ramesh:
To find the mass percent substitute the values in the equation.
The concentration of the solution is 9.09%.
Now Solution formed by Sarika:
To find the mass percent substitute the values in the equation.
The concentration of the solution is 10 %.
Therefore, by the calculation and value obtained it is clear that both the solutions are of different concentration.
Note:
The solution is formed by dissolving solute in the solvent. The substance which is added in the solvent is known as solute, the substance in which the solute is added is known as solvent and the combination of solute and solvent is known as solution.
