1. Write down a balanced equation for the reactions (CaCl2 and Na2CO3).
a) Determine the precipitate? Write its empirical formula?
2. Determine the mass of the dry precipitate. Determine the number of moles of precipitate produced in the reaction.
3. a. Determine the numbers of moles of Na2Co3 were present in the 15mL sample?
b. Determine the numbers of grams of Na2CO3 were present in the 15mL sample?
c. Determine the numbers of grams of Na2CO3 are present in the 575L of the Na2CO3solution? (Create a conversion factor to convert from the sample with a volume of 15mL to a solution with a volume of 575L.)
