Step 1: what's the molar mass of caffeine?
Using the Periodic Table, 12(8)+1(10)+14(4)+16(2)=194 g/mol.
Step 2: given 34.5 grams, how many moles is that?
34.5/1=194/x; solve for x to get 0.18 moles caffeine.
Step 3: how many molecules of caffeine is that?
0.18 moles times Avogadro's constant; 0.18(6.02x1023)=1.08x1023 molecules.
Step 4: how many carbon atoms is that?
Formula says 8 carbon atoms per molecule; 8(1.08x1023)=8.64x1023 carbon atoms.
This wasn't too hard because you didn't have to change up the scientific notation at all. Just watch your proper scientific notation format in you do have to change it.
