A freshly purified 1.32 g sample of the alpha particle emitting radionuclide 232Pa is prepared then placed inside a rigid 0.100 L evacuated container at 25.00C. Five days later the 4He pressure inside the container is 1.29 atm. What is the half-life for the alpha-decay of 232Pa (days)? Assume that the molar mass of 232Pa is 232 g/mole.
