CaCO3 can be roasted to produce CaO and CO2. This reaction is carried out in a flask connected to an open-end mercury manometer when the atmospheric pressure is 764 torr. If the pressure of the CO2 produced is 0.245 atm, determine the total pressure in the flask AND the height difference between the two arms of the manometer. I cant find the diference in height.

Solutions

Expert Solution

The total pressure inside the flask is calculated as

          Total Pressure = Atmospheric Pressure + Pressure of CO2

                                  = 764 torr + (0.245 * 760) torr

                                  = 764 torr + 186.2 torr

                                  = 950.2 torr

Height corresponding to pressure of 1 atm is 76 cm.

Thus, 0.245 atm pressure difference will show a height difference of (0.245 * 76) cm = 18.62 cm
