IT does not mention the observed yield PLEASE HELP ME Assume you perform the procedure outlined in the experiment “% Yield of Sodium Carbonate”. The reaction is as follows: NaHCO3(s) ® Na2CO3(s) + CO2(g) + H2O(g). You weigh out 1.4895 g baking soda (NaHCO3), heat it, and are left with 1.0026 g of solid (Na2CO3). What is the total mass of gases that was actually produced in the experiment? (Hint: During the reaction, gases will be released to the air....
