1. There are 6.02 x 10^23 molecules in a mole of CCl4 or a mole of anything else. So if one mole contains 6.02 x 10^23 molecules, how many molecules will be in 2 moles? 3 moles? 4 moles?
After you know how many molecules of CCl4 you have, look at the formula. There is 1 carbon atom per molecule of CCl4. So if you have 6.02 x 10^23 molecules of CCl4 and each one of those contains 1 atom of C, how many atoms of C will you have?
For Cl, notice you have 4 atoms of Cl for every molecule of CCl4.
Total atoms must be atoms C + atoms Cl.
