Understanding Specific Gravity

Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water at 4°C. Since the density of water is 1 g/mL, specific gravity is essentially the density of the substance expressed in g/mL.

Calculation

1. Density: Since specific gravity is 1.2, the density of the solution is 1.2 g/mL.

2. Volume: Use the formula:

Volume = Mass / Density

Volume = 185 g / 1.2 g/mL = 154.17 mL

Answer: The volume of the solution is approximately 154.17 mL.
