In the spectrum of oxalic acid the base peak is at 45 m/z since it is 100%. The molecular ion peak is in the spectrum it should be located at 126 m/z because it is dihydrated, with two molecules of water. But a small peak actually appears at 90 m/z corresponding to the molecular ion oxalic acid with a molecular weight of 90 g/mol.
Oxalic acid is dicarboxylic acid with basicity 2.So it would beequivalent weight = 90.03/2 = 45.015 g/molBut, in case you're dealing with oxalic acid dihydrate HOOC-COOH. 2 H2O then it be same as it's Molecular Mass ie. 126 g/molExplanation:In general the equivalent weight of a substance is calculated by dividing the Molecular Mass of the ...

Calculate amount of oxalic acid used To prepare 100 ml of 0.1 solution. 3 years ago Answers : (3) varun 304 Points hi tammana. you did not mentioned that it is 0.1N or 0.1M but i will explain you both. for molarity,,,, Oxalic acid=H2C2O4.2H2O. Molecular weight=126g/mol ... so M=weightx1000/molecular weight x vol.
The molecular mass of oxalic acid is calculated by adding the atomic mass of each constituent atom The molecular mass of H 2 C 2 O 4.2H 2 O = 126 Since the weight of oxalic acid that is required to make 1000 ml of 1M solution is 126 g. Hence, the weight of oxalic acid needed to prepare 250 ml of 0.1 M solution = 126/1000 x 250 x 0.1 = 3.15 g

Spinach is a good source of the omega-3 fatty acid known as alpha-linolenic acid (ALA), and its diacylglycerols can also contain the omega-3s stearidonic acid (SDA) and eicosapentaenoic acid (EPA). Of these three omega-3s, however, ALA appears to be the most consistently present and is present in the most readily measurable amounts.
