Hey there
Could anybody answer the following question on dust grains and depletion of Silicon and Carbon on dust:
If D(Si)=-3, D(C)=-0.5, and the logarithmic cosmic abundances of Silicon and carbon relative to H as 12 are 7.5 and 8.5 respectively, what is the ratio of the number of atoms of Si to C in dust grains?
I have an exam on Friday and I'm kind of stuck.
thanks
