How do you calculate moles from acid?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].
What is the formula for oxalic acid How did you determine this?
The formula of oxalic acid is (C2H2O4); its usual form is that of the crystalline hydrate, (COOH)2·2H2O. …
How do you find moles of NaOH with oxalic acid?
The molarity of the sodium hydroxide solution is 0.1632 M . In order for the oxalic acid to solution to completely neutralize the sodium hydroxide solution, you must add exactly 1 mole of oxalic acid for every 2 moles of sodium hydroxide.
What is the molar mass in g mol of oxalic acid?
90 g/mol
The molar mass of oxalic acid is 90 g/mol.
How do you calculate acid content?
The acid content of the must is determined by titrating a sample (a given volume) with a base such as sodium hydroxide solution to a phenolphthalein end point or alternatively, to a pH of 8.2. The titratable acidity is expressed as grams of tartaric acid per 100 ml.
How many moles of oxalic acid do you need?
Oxalic acid is a diprotic acid, you should have titrated the acid to the second equivalence point. Being a diprotic acid you need 2 moles of NaOH for every mole of the acid. I believe you’ll need the molarity of your standard solution of NaOH.
What is the molecular mass of oxalic acid?
Oxalic acid has its constant molecular mass of 90 g/mol. Oxalic acid generally form dihydrate molecule; hence, the molecular mass oxalic aicd dihydrate is 126 g/mol. , Asst. Prof. Of Chemistry/Biochemistry
How do you calculate the molar mass of a molecule?
Take a standard chemistry formula for a molecule, split it up into the component atoms, and look up the molar weight of each atom. Add the weight of the atoms in the molecule and you have the molar mass for the molecule.
