Use the mass of Na2CO3 measured at the beginning as given. You would need to refer to the balanced equation for this calculation. A B D F—— x —— x —— x——= answer 1 C E G
According to the balanced equiation for each 105.99 grams of Na2CO3, 2x58.44 grams of NaCl is produced (116.88 grams) so if we start with 0.575 grams of Na2CO3 we have the following result:
