> How massive would earth have been if it had accreted
hydrogen compounds in addition to rock and metal?
From the table, we can actually see that the relative
abundance of the compounds are:
Hydrogen compounds = 1.4%
Rock = 0.4%
Metal = 0.2%
Earth has only rock and metals therefore the total
percentage is (0.4 + 0.2)% = 0.6%.
Now if we are to include hydrogen compounds, so the new total is
(0.4 + 0.2 + 1.4)% = 2.0%
The ratio is then:
2.0% / 0.6% = 3.3
Therefore the Earth would be 3.3 times more massive.
> The same procedure of calculation is performed when we would like to include the Helium and hydrogen gas
