Can you please provide more clarification in the first part...I don't understand how to go from 153.8 g/mol of CCl4 and then dividing by Avogadro's number in molecules/mol. How are the grams cancelled out?
The grams are not part of the equation at that point. I just needed to convert the amount of molecules of CCl4 into moles. That is so I could multiply by the molar mass and have the moles cancel out just leaving the amount of grams.
