pTotal = patm - pwater height
h1d1 = h2d2
h1 = height of water = 30.2 mm
d1 = density of water = 1 g/cc
h2 = height of mercury = x mm
d2 = density of mercury = 13.6 mmhg
30.2*1 = x*13.6
x = 2.22 mmhg
pTotal = 746.8-2.22 = 744.58 mmhg
pWater = 18.8 mmhg
Ptotal = pN2 + Pwater
744.58 = pN2 + 18.8
pN2 = 725.78 mmhg

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 27.3 mm from the normal height, what is the atmospheric pressure (in Pa)? Normal atmospheric pressure is 1.013 ✕ 105 Pa and the density of mercury is 13.6 g/cm3. Answer should be in Pa
