Chemistry Pre-Lab Question..... Please show work for both questions and I will rate you. 1.)6.0 M NaOH is available in this laboratory. Calculate the amount of this reagent you will need in order to prepare 1.0 liter of 0.10 M NaOH. 2.) Calculate the grams of oxalic acid dihydrate (126.07 g/mol) needed to neutralize about 35 mL of approximately 0.10M NaOH. Hint. Write the balance chemical equation first between NaOH and H2C2O4. Use the above established path but in reverse starting with volume molarity of NaOH to find moles of NaOH and then ultimately grams of oxalic acid.

Explanation / Answer

1) M1V1 = M2V2 (6.0 M)(V1) = (0.10 M)(1.0 L) V1 = 0.0167 L = 16.7 mL of the 6.0 M NaOH Measure 16.7 mL of the original solution and add enough water to make 1.0 L of new solution. 2) Calculate the mass of oxalic acid dihydrate that would neutralize 35.mL of 0.10M NaOH solution. show all work. http://en.wikipedia.org/wiki/Oxalic_acid The information below is from the web site above! Oxalic acid is an organic compound with the formula H2C2O4. Typically oxalic acid occurs as the dihydrate with the formula C2O4H2
