ANSWERS: 1

I would suggest checking this but... this is how I think you'd get the answer: Write down the mass in grams for each element separately, which can be found on the periodic table. Then multiply the number by the subscript. For example if (this isn't the right number) one carbon is 1.222 multiply it by 8. Finally add all of the numbers together. Sorry if this is wrong. It's been a while since I last had chemistry!
