At 0.967 atm, the height of mercury in a barometer is 0.735 m. If the mercury were replaced with water, what height of water (in meters) would be supported at this pressure? The densities of Hg and H2O are 13.5 g/cm3 and 0.997 g/cm3, respectively.
Using a sample of gas has a mass of 38.7mg. Calculate the molar mass if its volume is 228mL at a temperature of 57°C and a pressure of 832torr?
