Depending upon the tip of a dropper pipet, there are approximately 20 drops per milliliter of water. The experimental procedure indicates the addition of 5-10 drops of each solution to the test tubes. Calculate the volume range in milliliters for the solution.
Can you please help me with this question?
Thank you!
If 20 drops to the mL then each drop is 1 mL/20 drops = 0.05 mL/drop.
Then 10 drops x 0.05 mL/drop = ? mL and
20 drops x 0.05 mL/drop = ? mL
To calculate the volume range in milliliters for the solution, we need to find the minimum and maximum number of drops for each solution.
Given that there are approximately 20 drops per milliliter of water, we can determine the volume range using the given range of 5-10 drops.
Step 1: Calculate the minimum volume range:
Minimum volume = 5 drops / 20 drops/mL
Minimum volume = 0.25 mL
Step 2: Calculate the maximum volume range:
Maximum volume = 10 drops / 20 drops/mL
Maximum volume = 0.5 mL
Therefore, the volume range for each solution is 0.25 mL to 0.5 mL.
To calculate the volume range in milliliters for the solution, we need to determine the minimum and maximum number of drops as indicated in the experimental procedure.
Given:
- There are approximately 20 drops per milliliter of water.
The procedure states:
- Add 5-10 drops of each solution to the test tubes.
To calculate the minimum volume range:
- Multiply the minimum number of drops (5) by the conversion factor of 1 milliliter per 20 drops.
- Minimum volume = 5 drops * (1 milliliter / 20 drops) = 0.25 milliliters
To calculate the maximum volume range:
- Multiply the maximum number of drops (10) by the conversion factor of 1 milliliter per 20 drops.
- Maximum volume = 10 drops * (1 milliliter / 20 drops) = 0.5 milliliters
Therefore, the volume range for the solution is approximately 0.25 to 0.5 milliliters.
