Answer:
The molecular mass of carbon dioxide is 44.01amu.
Explanation:
so, for 31 billion tons (28122726940000 kg),
it would be
44.01amu in grams is = 7.3080318e-23
which is = 7.3080318 * 10^-23 power
0.0000000000000073080318 grams
(I don't know any prefix for the above.)
31 billion tons in grams is = 2.812272694e+16
or 28122726940000000 grams
so 28122726940000000 grams * 0.0000000000000073080318 grams
is equal to ( = ) 0.00000205521 grams of carbon dioxide
= 1.2376765e+18
=123767650000000000 atomic mass units of co2
which is = atto 1.2376765
