The specific gravity of acetic acid (vinegar) is 1.049. State the density in units of pounds-mass per cubic foot.

Solution

A specific gravity means with reference to water, so the vinegar weighs 1·049 times as much as water. Find the density of water in pounds per cubic foot (reference books) and multiply that by 1·049
Perhaps you may find water\'s weight per gallon: you would then need to know how many gallons in a cubic foot. (again, reference books) You can get fussy over the temperature of the water too.
