The problem: CaCO3 can be roasted to produce CaO and CO2. This reaction is carried out in a flash connected to an open-end mercury manometer when the atmospheric pressure is 754 torr. If the pressure of teh CO2 produced is .100atm, determine the total pressure in the flask and the height difference between the two arms of the manometer.
