Hello, since you had submitted more than three sub-part in a question, so first three sub-parts shall be answered. But in this question mass of tube with NaCl product 882 g is not feasible for trail A, please check this data and submit this question again. Thanks. The number of moles is calculated as, Number of moles = massMolar mass Molar mass of Na2CO3 = 105.99 g/molThe net mass of reactant is calculated as, Net mass of reactant = Mass of tube with Na2CO3 - Mass of test tube and boiling chip. For trail A, Net mass of reactant = 861 g - 504 g = 357 g Number of moles of reactant = 357 g105.99 g/mol=3.368 mol For trial B, Net mass of reactant = 18.314 g - 17.969 g = 0.345 g Number of moles of reactant = 0.345 g105.99 g/mol= 0.0033 mol For trail C, Net mass of reactant = 18.186 g - 17.800 g = 0.386 g Number of moles of reactant = 0.386 g105.99 g/mol= 0.0036 mol The data and calculation of the given test tube A, B and C is shown below.
