Question

Malonic acid, H C H 04 (aq), is a diprotic acid, so 2 moles of hydroxide ions are required per mole of malonic acid for complete neutralization. Calculate the mass percent concentration of malonic acid using the molar concentration, 0.0950 M, and assuming the density of the solution is 1.01 g/mL?

Answer 1

You have given an incorrect formula for malonic acid. It is C3H4O4. It is an organic acid with a structure like this.... HOOC-CH2-COOH. Reaction with NaOH is as follows:

HOOC-CH2-COOH + 2NaOH ==> NaOOC-CH2-COONa + 2H2O

Now, even with the above information, we cannot answer the question since we DON'T KNOW THE MOLAR CONCENTRATION CALCULATED in PART B.
