Question

Calculate the concentration in terms of mass by volume percentage of the solution containing 2.5 g potassium chloride in 50 ml of potassium chloride (KCl) solution.

Answer 1

Mass of potassium chloride = 2.5 g

Volume of potassium chloride solution = 50 ml

Mass / Volume percentage = \(\frac{Mass\,of\,potassium\,chloride}{Volume\,of\,potassium\,chloride\,solution}\,\times\,100=\frac{2.5}{50}\,\times\,100=5\)%
