Answer 1

To calculate the volume of polysorbate 80 needed, divide the given mass of it (1 g) by its density (1.08 g/mL). The volume required is approximately 0.93 mL after rounding to two decimal places.

Step-by-step explanation:

The question asks us to calculate the volume of polysorbate 80 needed to fulfill a prescription, given the specific gravity of light mineral oil and polysorbate 80. Specific gravity is the ratio of the density of a substance to the density of a reference substance; in this case, water is the reference with a density of 1 g/mL. The specific gravity of polysorbate 80 is 1.08, therefore its density is 1.08 g/mL. To find the volume of 1 g of polysorbate 80, we use the formula:

Volume = Mass / Density

Volume = 1 g / 1.08 g/mL

Volume ≈ 0.9259 mL, which we round off to 0.93 mL of polysorbate 80.
