This is a fun problem to help realize why barometers were constructed with mercury rather than water! The density of mercury is 13.5 g/mL and the density of water is 1.00 g/mL. If a mercury barometer reads 679 mmHg, what is the barometric pressure in cmH, O? Hint: From physics we find that the pressure is related to the height according to the equation P = dgh where d = density, g gravitational acceleration and h is the height. %3D Now, if we have two devices at the same pressure we can say that P = digh = d2gh2 %3D

This is a fun problem to help realize why barometers were constructed with mercury rather than water! The density of mercury is 13.5 g/mL and the density of water is 1.00 g/mL. If a mercury barometer reads 679 mmHg, what is the barometric pressure in cmH₂O? Hint: From physics we find that the pressure is related to the height according to the equation \[ P = dgh \] where \( d \) = density, \( g \) = gravitational acceleration and \( h \) is the height. Now, if we have two devices at the same pressure we can say that \[ P = d_1gh_1 = d_2gh_2 \]
