A vehicle circulating on the seafront was a fire in the electrical principle. To extinguish the fire extinguisher was used a carbon dioxide (C02) 5-liter pressure mano metric equal to 70 atm at 20 ° C (298 k). How many moles of CO2 were injected, knowing that it was fully downloaded?

By stirring and heating, a group expelled virtually all the carbon contained in a liter of refrigenrante. Recolhids were 0.05 to 1.0 moles of gas atm.A measured volume of sample to provide a value of 0.5 L. Determine the temperature in K, which occurred this process.
