Question
Many solids used in the lab come with different variations for different purposes. For example, EDTA has
a formula of C1oH16N2O8 (292.2438 g/mol) but to improve the solubility of EDTA in water, the one we
used in the lab is EDTA disodium salt dihydrate "C10H14N2N22O8 •2H20 " (Molar mass: 372.24
g/mol)where there are two sodium atom and two water molecule attached to the EDTA, therefore, when
calculating the molar mass of EDTA, we need to add the mass of two sodium atoms and two water
molecule mass.
