Explain Please

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 731 mmHg, what is the barometric pressure in cmH_2O? 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 =d1gh1 = d2gH_2 Use this equation, your algebra skills and your logic to see how tall a water barometer would be!
