Two identical cylindrical vessels with their bases at the same level each contain a liquid of density 0.875 g/cm3. The area of each base is 4.11 cm2, but in one vessel the liquid height is 16.3 cm and in the other it is 22.2 cm. Find the work done by the gravitational force in equalizing the levels when the two vessels are connected.
 
W = mass x grav x height, so the height you want is (22.2-16.3)/2, then use that value.
mass = density / volume, and vol= area x the height you got.
So W = density x grav / area
