Question

Step 3: Add all of the atomic masses together to get the formula weight.

12.01 grams + 16.00 grams = 28.01 grams

? grams of Na + ? grams of Cl = formula weight

Step 4: To get the number of moles (FINAL ANSWER)

(mass of the package)/ (formula weight) = # of moles

(50 grams)/ (28.01 grams) = 1.8 moles

737 grams / ? grams of NaCl = ? moles NaCl

Question Two: How much mass is there of sodium ions? Chloride ions?

Step 5: CO has a 1:1 ratio of moles. There are 1.8 moles of Carbon and 1.8 moles of Oxygen
