UPSC NDA-1 – 2017
In this case, the mass of the solute (common salt) is 20 g, and the mass of the solvent (water) is 180 g.
The mass of the solution is the sum of the mass of the solute and the mass of the solvent: Mass of solution = 20 g + 180 g = 200 g.
Mass percentage of salt = (20 g / 200 g) * 100%.
