Question

A topical analgesic formulation requires 8 g of methyl salicylate (sp gr = 1.174). Convert this quantity to milliliters.

a) Pharmacological calculation
b) Physics experiment
c) Chemistry laboratory procedure

Answer 1

To convert 8 g of methyl salicylate to milliliters, divide the mass by the specific gravity.

Step-by-step explanation:

To convert 8 g of methyl salicylate to milliliters, we first need to determine its volume using its specific gravity. The specific gravity is a ratio of the density of a substance to the density of a reference substance (usually water). In this case, the specific gravity of methyl salicylate is given as 1.174, which means it is 1.174 times denser than water.

To calculate the volume in milliliters, we can use the formula:

Volume (mL) = Mass (g) / Specific Gravity

Substituting the given values:

Volume (mL) = 8 g / 1.174

Volume (mL) = 6.81 mL

Therefore, 8 g of methyl salicylate is equivalent to 6.81 mL.
