Question: Oxalic acid, H2C2O4*2H2O (molar mass = 126.07 g/mol) is oftenused as a primary standard for the standardization of a NaOHsolution. If 0.147 g of oxalic acid dihydrate is nutralizedby 23.64mL of a NaOH solution, what is the molar concentration ofthe NAOH solution?

2015年10月30日 · Oxalic acid is 26.68% carbon, 2.24% hydrogen, and the remainder oxygen, what is its empirical formula?

INTERACTIVE EXAMPLE Molar Mass and Moles References You have 21.5 g of oxalic acid, H2C204- What amount is represented by 21.5 g of oxalic acid? How many molecules of oxalic acid are in 21.5 g?

To determine the concentration of the oxalic acid standard solution, find the mass of oxalic acid by subtracting the mass of the empty beaker from the mass of the beaker with the oxalic acid.

Science Chemistry Chemistry questions and answers What mass of oxalic acid dihydrate, H2C2O4•2H2O, is needed to make a 0.357 M solution of oxalic acid in a 250.0mL volumetric flask? Note: The "•2H2O" part of the chemical formula given above indicates that the oxalic acid is hydrated; these are appropriately called "waters of hydration".
