TaigaTo calculate the number of moles in 5 grams of oxalic acid (C2H2O4), first determine the molar mass of oxalic acid, which is 90.03 g/mol. Then, divide the mass (5 grams) by the molar mass to get the number of moles. In this case, 5 grams is equal to approximately 0.055 moles of oxalic acid.

How many milliliters of a 0.270 M solution are needed to react completely with 3.245 g of oxalic acid?
To determine the volume of 0.270 M solution needed to react completely with 3.245 g of oxalic acid, first calculate the number of moles of oxalic acid (by dividing the mass by its molar mass). Then, use the mole ratio between the acid and the solution (from the balanced chemical equation) to find the moles of solution required. Finally, use the molarity to calculate the volume using the formula: volume (in liters) = moles / molarity. Convert the volume to milliliters, if needed.
Does tomato contain oxalic acid?
Yes, tomatoes do contain oxalic acid, although in relatively low amounts compared to other foods like spinach and rhubarb. Oxalic acid is a naturally occurring compound found in many fruits and vegetables.
Are ascorbi acid and oxalic acid same?
No, ascorbic acid (vitamin C) and oxalic acid are different compounds. Ascorbic acid is a water-soluble vitamin found in many fruits and vegetables, while oxalic acid is a plant-derived compound found in foods such as spinach and rhubarb. Oxalic acid can form crystals in the body in high concentrations and may contribute to kidney stone formation.
How many ionoization constant are associated with oxalic acid?
Oxalic acid (H2C2O4) has two ionization constants since it can donate two protons. The ionization constants represent the extent to which the acid dissociates in water to form ions.
How do you prepare 100ml 0.1M of oxalic acid solution?
To prepare 100 ml of 0.1M oxalic acid solution, you would need to dissolve 0.63g of oxalic acid dihydrate (H2C2O4 · 2H2O) in a sufficient amount of water, and then make up the volume to 100 ml. Oxalic acid dihydrate has a molar mass of 126.07 g/mol.
