In Example 4, the molar amount of NaCl computed in the first step, mol, would be properly rounded to mol if it were to be reported; however, although the last digit (5) is not significant, it must be retained as a guard digit in the intermediate calculation. If we had not retained this guard digit, the final calculation for the mass of NaCl would have been g, a difference of g.
