How do you calculate moles of oxalic acid?
Since oxalic acid is a dicarboxylic acid, 1 mole of acid reacts with 2 moles of NaOH. So by actual experiment 0.0179 x (1/2) = 0.00895 mol of acid was present. (. 98 g) / (90.0352 g H2C2O4/mol) = 0.01088 mol H2C2O4 is what was stared with, which compares roughly with what was determined by titration.
How do you find the molar mass of an acid?
For instance, you can find the molar mass of an acid by titrating the acid with a solution of base of known concentration. What is the molecular weight of an unknown monoprotic acid if 0.4955 g of the acid are neutralized by 37.00 mL of a 0.1000 M NaOH solution?
What is the molar concentration of oxalic acid?
Answer: The molarity of oxalic acid solution is 0.05 M.
How is the molar mass of oxalic acid 126?
Now, we know the molar mass and mass of oxalic acid. Molar mass is 126gmol−1and mass is 12.6 g.
What is the molecular formula of oxalic acid?
The formula of oxalic acid is (C 2 H 2 O 4 ); its usual form is that of the crystalline hydrate, (COOH) 2 ·2H 2 O. Known as a constituent of wood sorrel as early as the 17th century, oxalic acid was first prepared synthetically in 1776.
What is the gram molecular mass of oxalic acid?
If you are talking about acid bace reactions then equivalent mass of oxalic acid is 45g/mole. Molecular mass of H2C2O4 (oxalic acid) is 90g/mole. But it can neutralize 2 moles of base.
Answer and Explanation: The molar mass of hydrochloric acid is 36.46 g/mol. The first step in calculating the molar mass is to determine the molecular formula of the compound. Hydrochloric acid has a molecular formula of HCl. Then, add the atomic mass of all the element. 1 H = 1.01 g/mol. 1 Cl = 35.45 g/mol.
What is the equation for molar mass?
Empirical formula weight = (1 x 12.01g/mol) + (2 x 1.01g/mol) + (1 x 16.00g/mol) = 30.02g/mol. Divide the molar mass for the molecular formula by the empirical formula mass. The result determines how many times to multiply the subscripts in the empirical formula to get the molecular formula.
