Question: A mixture sample containing 80% NaHCO 3 and 20% NaCl was marketed for certain food preparations. As an analytical chemist, you took a 2.00 g

A mixture sample containing 80% NaHCO₃ and 20% NaCl was marketed for certain food preparations. As an analytical chemist, you took a 2.00 g of the mixture and heated it until the decomposition reaction was complete and found the final mass was 1.02 g. Based on this, calculate the percent of NaHCO₃ in the mixture. Assuming 80% is the actual value, what is the percent error in your measurement?
