if the barometric pressure is 741 mmHg, and if h = 53. 0 mm, what is the pressure of the gas, expressed in atm and in kilopascals, if the substance in the tube is mercury having a density of 13.6 g/mL. If we replace the mercury with water, what will be the value of "h" assuming the gas pressure and barometric pressure are the same? density of water is 1.00 g/mL
