Torricelli, who invented the barometer, used mercury inits construction because mercury has a very high density,which makes it possible to make a more compact barometerthan one based on a less dense fluid. Calculate the densityof mercury using the observation that the column of mercury is 760 mm high when the atmospheric pressure is1.01 x 105 Pa. Assume the tube containing the mercury isa cylinder with a constant cross-sectional area.
