Hi all
I seem to have a recurring problem with this type of calculation:
We have to calculate the increase in percentage in the mass of carbon in the atmosphere if we were to move 1ppm of the rock reservoir to the atmosphere (without compensating transfer of carbon out of the atmosphere)
The data is Mass of carbon/10¹²kgC for rock is 50,000,000 x 10¹² KgC and in the atmosphere is 800 x10¹²kgC.
The calculations given by the book is as follows:
1ppm: is 1 x10⁶( elevated at six) so divide 50,000,000 x 10¹²/1 x10⁶= 50 x 10¹²
50 x 10¹²/ 800 x 10¹²x100%=6.3%
Sorry I know this is too basic but I don't get the first part of the calculation.
I have the same sort of problem with this other calculation , not sure where the 17 is coming from
1370 W m⁻² x1.27 x10¹⁴ m²= 1.74 x10¹⁷ W
Any comments would be great
Thanks
