a liquid has a specific gravity of 0.357. What is its density?

Answer 1

The density is 0.357 g/mL. This is because specific gravity is the ratio of the density of the unknown liquid to the density of water, 1.0 g/mL.

If, say, you wanted to know the density of the liquid in pounds per gallon, you would multiply 0.357 by the density of water, which is 8.320 lb/gal
