CHEMISTRY HWK MAKES NO SENSE -
I thought it made goo sense.
How many moles C3H8 do you have in 464.99 g? That is 464.99/molar mass C3H8 = ?mols C3H8
How many mols C are in ?mols C3H8. Mols C = 3*mols C3H8 because there are 3 atoms of C in 1 molecule C3H8.
Now convert mols C to grams C. g = mols C x atomic mass C.
