After the synthesis, your group will propose possible product formulae and calculate the percent yield for each using the actual yield you obtain from your purified product crystal mass. If you were to conduct the synthesis described in the previous question, and one of your possible product formulae was Na2CoCl 4, you could determine the percent yield (assuming it was the correct product). Assuming that cobalt (II) chloride hexahydrate is the limiting reactant, calculate the percent yield of the product if 5.1 g of starting material were used and the product mass was 1.6. Enter your answer to one decimal place.
