Questions and Answers

What is the definition of mass percentage (w/w) of a component in a solution?

  • Mass % of a component = Mass of the component in the solution + Total mass of the solution
  • Mass % of a component = (Mass of the component in the solution / Total mass of the solution) x 100 (correct)
  • Mass % of a component = (Total mass of the solution / Mass of the component in the solution) x 100
  • Mass % of a component = Mass of the component in the solution - Total mass of the solution
  • In which situations is qualitative description of concentration inadequate?

  • When dealing with industrial chemical applications
  • When precise quantitative information is needed (correct)
  • When discussing dilute solutions
  • When discussing concentrated solutions
  • What does it mean when a solution is described as '10% glucose in water by mass'?

  • 10 g of water is dissolved in 90 g of glucose resulting in a 100 g solution
  • 10 g of glucose is dissolved in 10 g of water resulting in a 20 g solution
  • 10 g of glucose is dissolved in 90 g of water resulting in a 100 g solution (correct)
  • 10 g of water is dissolved in 90 g of glucose resulting in a 200 g solution
  • Why is quantitative description necessary for describing concentration?

    Study Notes

    Concentration of Solutions

    • Mass Percentage (w/w): The proportion of the mass of a component in a solution to the total mass of the solution, expressed as a percentage.

    Limitations of Qualitative Description

    • Inadequate situations: Qualitative description of concentration is insufficient when accurate measurements are required, such as in scientific research, medical applications, and precise chemical reactions.

    Solution Composition

    • '10% glucose in water by mass': Means that 10 grams of glucose are present in every 100 grams of the solution, which is a quantitative description of the concentration.

    Importance of Quantitative Description

    • Necessity: Quantitative description is necessary for describing concentration because it provides precise and accurate measurements, which are crucial in various scientific and practical applications.

    Volume Percentage (V/V)

    • Definition: The proportion of the volume of a component in a solution to the total volume of the solution, expressed as a percentage.
