Based on the rise of the boiling point, the molar mass of benzoic acid in the solution is 251.3 g/mol.
What is Elevation in boiling point?
When a chemical is added, the boiling point of a liquid (a solvent) will rise, which means that a solution has a higher boiling point than a pure solvent. This phenomenon is known as boiling-point elevation.
The relationship between the solution's solute content and its rising boiling point is straightforward (Tb).
Given:
Mass of benzoic acid= 5.0g
to find molar mass:
Therefore after calculation , benzoic acid has a molar mass of 251.3 g/mol.
