The answer depends on which compound is in the 0.270M solution to react with oxalic acid, and sometimes also at what temperature and pH value this reaction is taking place.

Oxalic acid is generally warmed slightly because it is not completely soluble and heat helps this. It aids in accuracy of the titration.
1 gram Oxalic Acid in 7 ml of water at room temperature - 1 gram per 2 ml of hot water will provide saturated solution.
Yes, it is possible to prepare oxalic acid by adding hcl to a solution og sodum oxalate. The balance equation would be C2O4Na2 + 2HCl -----> 2NaCl + C2O4H2.

No we cannot prepare Oxalic acid by the given method. Solubility of Sodium Oxalate is less in comparison to solubility of Oxalic acid. So whatever oxalic acid is formed will remain in the solution and cannot be precipitated out in the form of solid
Oxalic acid (M.W.= 90 g/mol) is available in the lab as oxalic acid dihydrate crystals (M.W. = 126 g/mol). A standard solution of Oxalic acid or ethandioic acid can be used as a standard solution to standardise other alkali solutions because oxalic acid crystals are non-hygroscopic in nature. To prepare a 1 liter 1N solution of oxalic acid, follow these steps: 1. Carefully weigh 0.5 mol or 63 g of oxalic acid dihydrate crystals. This is because th n-factor of oxalic acid is 2 and so 1 mole of oxalic acid = 2 equivalents of oxalic acid. 2. Wash the 1 litre volumetric flask first with tap water (thrice), then with chromic acid solution (once but thoroughly) and finally with distilled water so as to remove any contaminants from the glassware. 3. Pour the crystals in the volumetric flask and add some distilled water. Shake the mix to dissolve the crystals in the solvent. 4. Make-up the volume to 1-litre by adding more distilled water.
The normality of 1M oxalic acid is 1N. This means that every mole of oxalic acid in 1 liter of solution has the capacity to donate or accept 1 equivalent of acid-base species.

MnO2 gets reduced by the reducing agent (in this case oxalic acid). But i do think the solution needs to be acidified to provide a anion ion for the Mn2+ ions that will be produced.
Oxalic acid is a stable compound.
