- A. 0.030 dm³
- B. 0.300 dm³
- C. 3.00 dm³
- D. 0.0030 dm³
Answer
0.030 dm³
Explanation
To convert cm³ to dm³, divide by 1000. Therefore, 30.0 cm³ = 30.0 / 1000 = 0.030 dm³.
Common mistake
Using Incorrect Titre Values
Students often use individual titre values instead of the mean titre value when calculating concentrations.
To fix this, calculate the mean titre value by adding all titre values and dividing by the number of titres. Then use the mean titre in your calculations. For example, if the titres are 25.0 cm³, 25.2 cm³, and 24.8 cm³, the mean titre is (25.0 + 25.2 + 24.8) / 3 = 25.0 cm³. Use this mean titre in your concentration calculations.
