Propane gas is used as a propellant in aerosol cans.
a. Suppose a 455 mL container contains propane gas at a pressureof 1.75 atm at 25.0 ^oC. How many grams of propane are inthe container?
b. If the can in part a is cooled to 5.0 ^oC and anadditional 10.0 grams of propane is added to the can, what is thepressure of the propane gas? How does this pressure compare to theoriginal pressure in part a? Whose law(s) explains this change anduse the postulates of Kinetic Molecular Theory to explain thechange.
c. If all the propane in the original can (as described in parta) were transferred to a balloon at STP, what volume would thepropane occupy? How does this compare the original conditions inpart a? Explain in terms of Kinetic Molecular Theory and gaslaws.
d. The can in part a says that it can handle a pressure of 5.00atm without bursting. What is the maximum mass of propane the canis able to hold before bursting? Whose law describes therelationship and explain the change using Kinetic MolecularTheory.
e. The can in part a says that it can handle a pressure of 5.00atm. What is the maximum temperature to which the propane can beheated to without bursting.
