You are given an unknown mixture containing NaCl and NaHCO3. When you carry out the heating exactly as described decomposing NaHCO3, only NaHCO3 decomposes. From the loss in mass, you can calculate the amount of NaHCO3 present in the mixture and its mass percent composition. Experimental data Unknown (NaCl + NaHCO3) Mass of crucible + cover 72.42 g Mass of crucible + cover + mixture 74.80 g Mass of crucible + cover + residue (1st heating) 74.25 g Mass of crucible + cover + residue (2nd heating) 74.24 g Mass of crucible + cover + residue (3rd heating) 74.24   From the data above, carry out your calculation for finding the mass of mixture, and mass of final solid remaining in the crucible. Using the knowledge that only loss of mass due to CO2 and H2O can be linked to the original mass of NaHCO3, calculate the mass of NaHCO3 and percent of NaHCO3 in the mixture.
