An acid with molecular mass 104 contains 34.6% carbon 3.85% hydrogen and rest is oxygen the molecular formula of acid is:
Correct answer: A. C3H404.
- A. C3H404.
- B. C2H2O.
- C. C2H2O4.
- D. C2HO2.
Explanation
C : H : O 34.6/12 :3.5/1 : 61.5/16 3 : 4 : 4 => E:F= C3H4O4 =>E.F.Mass= (3x12)+(1x4)+(4x16) = 104 => n= Molecular Mass/ E.F.Mass = 104/104 =1 => Molecular formula= n x E.F = 1 x C3H4O4 = C3H4O4.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
