Molar mass of formic acid in benzene comes out to be:
Correct answer: D. 92
- A. 64
- B. 46
- C. 32
- D. 92
Explanation
Option D is the correct molar mass of formic acid (HCOOH) in benzene. To calculate the molar mass, we add the atomic masses of each element present in the compound: Hydrogen (H) + Carbon (C) + Oxygen (O) + Oxygen (O) + Hydrogen (H). The molar mass of formic acid (HCOOH) is 46 g/mol.Here's the calculation:H = 1 g/molC = 12 g/molO = 16 g/mol Molar mass of HCOOH = (H + C + O + O + H) = (1 + 12 + 16 + 16 + 1) = 46 g/mol. since they exist as dimers in the organic solvents e.g benzene their mass will calculated as double so 46+46 is 92 so option D is correct

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
