year. Assume the molecular weights of carbon, calcium,
and oxygen are 12.011 g mol 1 , 40.078 g mol 1 , and
15.9994 g mol 1 ,respectively. By what factor would
the world's quicklime production need to be increased
to remove all anthropogenic CO 2 (g) in 2010 if the 2010
quicklime production was about 2.83

dwells in out-of-the-way
places”

(e) Theophrastus (5) “plaster”
(f) Paracelsus (6) “water maker”
(g) Van Helmont (7) “lazy gas”

1.9. The atmosphere contained approximately 115
ppmv of anthropogenic CO 2 (g) in 2010. If 1 ppmv-
CO 2 (g) is equivalent to 2184.82 Tg-C (teragrams, or
