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

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.
