Data Analysis 1. Assuming your unknown is NaHCO3, use stoichiometry to calculate the theoretical yield of
solid NaCl for the reaction represented by Equation (1).
Use your mass of unknown solid weighed out in the lab as the starting point and the mole
ratio from Equation (1). Show work.
Theoretical mass or yield of NaCl if unknown is NaHCO3
NaHCO3(8) + HCl(aq)
NaCl(aq) + H200) + CO2(g)
