A 21.8L tank of carbon dioxide (C02) is at a pressure of 8.91 atm and temperature of 19.4\" C. 0) Calculate the number of moles of gas in the tank. mol ( i 0.02 mol) (b) Obtain the number of grams of carbon dioxide in the tank. Hint: You R) can obtain the molar mass of C02 by adding the molar mass of C and twice the molar mass of O. The molar mass of an element is given on the periodic table in units of grams! mole. g(i28) A re breaks out, raising the ambient temperature to 69.1 C while 82.3 g of gas leak out of the tank. Calculate the nal pressure in the tank as a result of the re and leakage. Hint: Use R =0.0821 L'mm for the gas moi-K constant in the ideal gas law. This allows you to use liters for volume and atmospheres for pressure. atm ( i 0.02 atm)
