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 721 mmHg, what is the barometric pressure in cm \( \text{H}_2\text{O} \)? 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. Now, if we have two devices at the same pressure, we can say that \[ P = d_1g h_1 = d_2g h_2 \] Use this equation, your algebra skills, and your logic to see how tall a water barometer would be! Barometric pressure: [__________] cm \( \text{H}_2\text{O} \)
