### How much does a gallon of sulfuric acid weigh?

It depends how concentrated it is.
If it is 100% pure, then it weighs 1.840 g/mL, and so 1 gallon
weighs 6965.15 g, or 6.965 kg (3785.41 mL per gallon). That's equal
to 15.35 lbs.
However, it is VERY unlikely that you actually have completely pure
H2SO4, and at most normal concentrations, the density of sulfuric
acid is very close (but slightly more) than that of water. A gallon
of water weighs 8.345 lbs. So a gallon of dilute sulfuric acid will
weigh about 8.5 lbs, and a very concentrated solution will weigh
close to 15 lbs.

###### Asked in Acids and Bases

### What is the weight per gallon of inhibited hydrochloric acid?

Since the inhibitor is almost always a very small addition, the
density of inhibited hydrochloric acid is very close to the same as
for uninhibited hydrochloric acid.
The density depends on the concentration of hydrochloric acid --
stronger acid is heavier.
To convert density (kg/l) to pounds per gallon, multiply by
8.34.
