prove that the Density of air at STP (0◦C, 760 torr) = 1.293 kgm–3
the density of air at 0degree C and 760 torr is 1.2929gL^-1, and the density O2 under the same conditions is 1.4290gL^-1. Briefly explain why the O2 remains in the fifth covered bottle while you do experiments with the O2 collected in the second, third, and forth bottles.

6.15. An aluminum ionization chamber containing 10 cm3 air at 20°C and 760 torr operates under Bragg-Gray conditions. After a 1-hour exposure to 6oCo gamma rays, 3.6 x 10-9 C of charge is collected. If the relative mass stopping power of Al for the electrons generated by the 60Co gammas is 0.875, what was the dose to the aluminum?
