Homework Statement
The mass of silicon in the Earth is estimated to be 7x10^23 kg. The ratios of the masses of Hyrdogen and Helium to silicon in the sun are: H/Si = 850, He/Si = 250. Calculate the mass of the the body thatwould have been produced if H and He had been added to the Earth (present day mass M_E = 6x10^24 kg) in the smae proportions to Si as they are in the sun, esxpressing your answer as a multiple of M_E. How does this result compare with the mass of Saturn (= 100M_E)
Homework Equations
The Attempt at a Solution
does this question need me to convert the masses into number of molecules, or do I simply times the mass of Silicon by 250 and 850, and adde it to the mass of the the Earth?
Any help would be most appreciated,
