Is Matter Around Us Pure — Question 3

Given,

Mass of solute (NaCl) = 36 g

Mass of solvent (H₂O) = 100 g

Mass of solution (NaCl + H₂O) = 100 + 36 = 136 g

Concentration = $\dfrac{\text{Mass of solute}}{\text{Mass of solution}}$ x 100

Concentration = $\dfrac{36}{136}$ x 100 = 26.47%

Hence, the concentration of the solution is 26.47%
