Solution

$N a C l$ is solute and water is solvent because solute is generally present in less quantities then solvent. Also, the substance which is dissolved is called solute whereas the substance in which it is dissolved is called solvent.
concentration = [Mass of solute ( $N a C l$ ) $\times$ 100 ]/ mass of solution.
Mass of solute = 36 g.
Mass of solution = mass of solvent + mass of solute = 100 + 36 g = 136 g
Concentration = (36 x 100) / 136= 3600/136 = 26.47 %
