A cylindrical tank has a height of 3.72 m and 1.32 m in diameter. The tank contains 6,950 kg of Cl2, 28.64 kg of CO2 and 13,73 kg of N2. All of these gases are at a temperature of 21.6 *C. What is the pressure in manometer if the barometer indicate 99.5 kPa and the molar masses of the gas are MCl2 = 70,906 g/mol, MCO2 = 44,0098 g/mol and MN2 = 28,0134 g/mol?
