Understanding Concentration of a Solution
Concentration is a measure of how much solute is present in a given quantity of solvent or solution. It is often expressed in terms of mass percentage, which indicates how much of the solute is present in 100 grams of the solution.
Components of the Given Solution
- Solute: Common salt (NaCl)
- Mass of solute (salt): 40 grams
- Mass of solvent (water): 320 grams
Calculating Total Mass of the Solution
To find the concentration, we first need to calculate the total mass of the solution:
- Total Mass = Mass of solute + Mass of solvent
- Total Mass = 40 grams (salt) + 320 grams (water)
- Total Mass = 360 grams
Calculating Mass by Mass Percentage
The mass by mass percentage is calculated using the formula:
- Mass percentage of solute = (Mass of solute / Total mass of solution) × 100%
Substituting the values:
- Mass percentage of salt = (40 grams / 360 grams) × 100%
- Mass percentage of salt = (0.1111) × 100%
- Mass percentage of salt = 11.11%
Final Result
The concentration of the solution in terms of mass by mass percentage is:
- 11.11%
This means that in every 100 grams of the solution, approximately 11.11 grams is common salt. Understanding this concept is crucial in chemistry, particularly in preparing solutions for various applications.
