A 16.4-L tank of carbon dioxide gas (CO2) is at a pressure of 8.30105 Pa and temperature of 17.6°C.
(a) Calculate the temperature of the gas in Kelvin.
1 K
(b) Use the ideal gas law to calculate the number of moles of gasin the tank.
2 mol
(c) Use the periodic table to compute the molecular weight ofcarbon dioxide, expressing it in grams per mole.
3 g/mol
(d) Obtain the number of grams of carbon dioxide in the tank.
4 g
(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 5 K
number of moles 6 mol
(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 n_i for ni, the initial number ofmoles, n_f for nf, the final number of moles, T_i for Ti, theinitial temperature, T_f for Tf, the final temperature, and P_i,for Pi, the initial pressure as appropriate.)

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