A solution contains 20g of solute in 180g of solvent. If the solvent is water, what is the concentration of the solution in terms of mass by mass percentage

  • A 11.%
  • B 22.2%
  • C 10%
  • D 20%

The correct answer is C. 10%

Mass of Solution = Mass of Solute + Mass of Solvent â†’ 20g + 180g

: Mass of Solution = 200g

Mass Percent = \(\frac{Mass of Solute}{Mass of Solution} * 100%\)

Mass percent = \(\frac{20}{200} * 100%\)

Mass percent = 10%
