Question

What is the concentration in terms of mass percent of a solution in which 40 g of salt is dissolved in 200 mL of water?


  1. 20 %

  2. 16.66 %

  3. 25.0 %

  4. 12.5 %


Solution

The correct option is B

16.66 %


1 mL of water has a mass of 1 g. So, mass of 200 mL of water = 200g

Mass of the solution = mass of the solute + mass of the solvent = 200 + 40 = 240 g

Mass percentage of a solution = mass of the solutemass of the solution×100%= 40 g240×100%=16.66 %
