Question

Step 6:

Determine the mass of carbon ions:
(1.8 mol C)x (12.01 grams C)/ (1 mol) = 21.6 grams of C

( ? mol Na) X ( ? grams Na) / (1mol) = ? grams of Na

Determine the mass of oxygen ions:
(1.8 mol O) x (16.00 grams O)/(1 mol) = 28.8 grams of O

( ? mol Cl) X ( ? grams Cl) / (1mol) = ? grams of Cl

*Check your answer: take the mass of the carbon ions plus the mass of the oxygen ions to get the mass of the container.*

21.6 grams of C + 28.8 grams of O = 50 grams (the weight in the container)

Question Three: What percentage of the total mass is sodium? Chlorine?
