Final answer:
To find the volume occupied by the drops, divide the mass of the drops by the density of the essential oil. In this case, the volume is 0.626857 cm³.
Step-by-step explanation:
To find the volume occupied by the drops, we need to use the formula: density = mass/volume. Rearranging the formula, we have: volume = mass/density.
Given that the mass of 20 drops is 548.0 mg and the density is 0.875 g/cm³, we first need to convert the mass to grams by dividing it by 1000. Then, we can calculate the volume by dividing the mass by the density.
Volume = (548.0 mg ÷ 1000) / (0.875 g/cm³) = 0.626857 cm³
