Compare the masses of potassium hydrogen phthalate (204.22g/mol); potassium hydrogen iodate (389.91g/mol); and benzoic acid (122.12g/mol) needed for a 300.00mL standardization of 0.0400M NaOH. What would the relative standard deviation in the molarity of the base if the standard deviation in the measurement of mass is 0.002 g and this uncertainty limits the precision of the calculation?
