How tall would the barometer be?
![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 751 mmHg, what is the barometric pressure in cm H₂O?
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
\[ P = d_1 g h_1 = d_2 g h_2 \]
Use this equation, your algebra skills, and your logic to see how tall a water barometer would be!
