Because of increasing evidence of damage to the ozone layer, chlorofluorocarbon (cfc) production was banned in 1996. however, there are about 100 million auto air conditioners that still use cfc−12 (cf2cl2). these air conditioners are recharged from stockpiled supplies of cfc−12. if each of the 100 million automobiles contains 1.2 kg of cfc−12 and leaks 20 % of its cfc−12 into the atmosphere per year, how much chlorine, in kg, is added to the atmosphere each year due to auto air conditioners? (assume two significant figures in your calculations.)

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
