A 22.7-L tank of carbon dioxide gas (CO2) is at a pressure of 9.00105 Pa and temperature of 20.9°C.
(a) Calculate the temperature of the gas in Kelvin.
293.9K
(b) Use the ideal gas law to calculate the number of moles of gasin the tank.
?
(c) Use the periodic table to compute the molecular weight ofcarbon dioxide, expressing it in grams per mole.
44g/mol
(d) Obtain the number of grams of carbon dioxide in the tank.
?
(e) A fire breaks out, raising the ambient temperature by 224.0 Kwhile 82.0 g of gas leak out of the tank. Calculate the newtemperature and the number of moles of gas remaining in thetank.
temperature 517.9
number of moles
(f) Using a technique analogous to that in Example 10.6b, find asymbolic expression for the final pressure, neglecting the changein volume of the tank. (Use the following as necessary: ni, theinitial number of moles, nf, the final number of moles, Ti, theinitial temperature, Tf, the final temperature, and Pi, the initialpressure as appropriate.)

(g) Calculate the final pressure in the tank as a result of thefire and leakage.
