What mass of oxalic acid dihydate, H2C2O4•2H2O, is needed to make a 0.498 M solution of oxalic acid in a 250.0 mL volumetric flask? Note: The “•2H2O” part of the chemical formula given above indicates that the oxalic acid is hydrated; appropriately, these are called “waters of hydration”. You must add the mass of this water to the oxalic acid when calculating its molecular mass.
