phase 3: volume of a drop
complete the following steps
while counting drops, add drops of water up to 1 ml mark on the graduated cylinder
record number of drops in lab data
calculate average drop volume. record in lab data
go to phase 4

Explanation:

To calculate the average drop volume, we use the formula for the average: the total volume divided by the number of drops. From the lab data, the water volume is 1 mL, and the number of drops is 15 (assuming the "15" is the number of drops to reach 1 mL, as the table shows "Number of drops" as 15 for 1 mL water volume).

Step 1: Identify the total volume and number of drops

The total volume of water is \( V = 1 \, \text{mL} \), and the number of drops is \( n = 15 \).

Step 2: Calculate the average drop volume

The formula for the average drop volume \( v_{\text{avg}} \) is \( v_{\text{avg}} = \frac{V}{n} \). Substituting the values, we get \( v_{\text{avg}} = \frac{1}{15} \approx 0.0667 \, \text{mL per drop} \).

Answer:

The average drop volume is approximately \( \frac{1}{15} \, \text{mL} \) (or \( 0.0667 \, \text{mL} \)) per drop.
