)if mercury (density = 13.6 g/cm3) at a height of 745 mm hg in a mercury barometer is replaced with water (density = 1.00 g/cm3), under the same conditions the height of water will be

The answer to this question would be: 10132 mm= 33.2 ft

In this question, the density of mercury is 13.6 times of water which mean the mercury mass is also 13.6 times more than water. The pressure is directly influenced by mass, so the water height should be much higher than mercury. The calculation should be: 745mm * 13.6/1= 10132 mm= 33.2 ft

It will fall off and tip over.
