As a thunder storm passes through a region, there is an associated drop in atmospheric pressure. If the height of a mercury barometer drops by 16.1 mm from the normal height, what is the atmospheric pressure (in Pa)? Normal atmospheric pressure is 1.013 x 105 Pa and the density of mercury is 13.6 g/cm3 (NOTE: This is g/cm^3, not SI units of kg/m^3).
