Calculate the relative standard deviation in the computed molar concentration of 0.0200 M HCl if this acid was standardized against the masses found in Example for (a) TRIS, (b) Na2CO3, and (c) Na2B4O7.10H2O. Assume that the absolute standard deviation in the mass measurement is 0.0001 g and that this measurement limits the precision of the computed concentration.
