potassium hydrogen phthalate is a primary standard used to measure the concentration of NaOH solutions. find the true mass of potassium hydrogen phthalate (density=1.636g/ml) if the mass weighed in the air is 4.236g. if you did not correct the mass for buoyancy, would the calculated molarity be too high or too low? the density of air is 0.0012 g/mL while that of the calibration weights is 8.0 g/mL.
