Answer:
20 drops
Explanation:
Step 1: Given data
Step 2: Calculate the volume of water added
We calculate the volume of water added by subtracting the initial volume to the final volume.
36.0 mL - 23.0 mL = 13.0 mL
Step 3: Calculate the number of drops in 1 mL
We will divide the number of drops of water added by the volume they represent.
265 drops / 13.0 mL = 20.4 drops/1 mL ≈ 20 drops/1 mL
