20. The (v/v) % of a solution containing 5 ml of alcohol in 40 ml. of ...
Understanding (v/v) % Concentration
In the context of solutions, (v/v) % refers to the volume of solute per total volume of solution, expressed as a percentage.
Calculation Steps
- Determine the Volume of Solute:
- In this case, the volume of alcohol (solute) is 5 ml.
- Determine the Total Volume of Solution:
- The total volume is the sum of the volume of alcohol and the volume of water.
- Total Volume = Volume of Alcohol + Volume of Water
- Total Volume = 5 ml + 40 ml = 45 ml.
- Calculate (v/v) %:
- The formula for (v/v) % is:
- (Volume of Solute / Total Volume of Solution) × 100
- Plugging in the values:
- (5 ml / 45 ml) × 100 ≈ 11.11%.
Final Result
- After performing the calculations, the (v/v) % of the solution is approximately 11.11%.
Choosing the Correct Option
- From the options provided:
- (a) 14.29%
- (b) 12.5%
- (c) 11.11%
- (d) 10%
- The correct answer is (c) 11.11%.
This calculation illustrates how to determine the (v/v) % concentration of a solution effectively.
