Answer:
The correct answer is option (b)
Step-by-step explanation:
Molar Mass or Molecular mass of a compound is defined as the total mass of the atoms with which the compound is made of. It is represent in grams
Oxalic acid, also known as Ethanedioic acid, is an organic acid with chemical formula C₂H₂O₄
Oxalic acid with two water of crystallization, is given by the formula
C₂H₂O₄ . 2H₂O, which contains 2 atoms of carbon, 6 atoms of hydrogen, and 6 atoms of Oxygen
We know that the The atomic mass of Carbon, Hygrogen and oxygen are respectively 12g/mole, 1g/mole and 16g/mole
Hence,
Weight of 2 Carbon atom = 2×12 = 24g/mole
Weight of 6 Hydrogen atom = 6×1 = 6g/mole
Weight of 6 Oxygen atom = 6×16 = 96g/mole
Total mass of 2 atoms of carbon, 6 atoms of hydrogen, and 6 atoms of Oxygen = 24+6+96
=126g/mole
∴ The molar mass of oxalic acid is 126g/mol
The correct answer is option (b)
