A 17.0-L tank of carbon dioxide gas (CO2) is at a pressure of 9.90 ✕ 105 Pa and temperature of 15.0°C.

(a) Calculate the temperature of the gas in Kelvin.
____K

(b) Use the ideal gas law to calculate the number of moles of gas in the tank.
___ mol

(c) Use the periodic table to compute the molecular weight of carbon dioxide, expressing it in grams per mole.
___ g/mol

(d) Obtain the number of grams of carbon dioxide in the tank.
___ g

(e) A fire breaks out, raising the ambient temperature by 224.0 K while 82.0 g of gas leak out of the tank. Calculate the new temperature and the number of moles of gas remaining in the tank.
