Class 12 Chemistry Chapter 2 Numericals | Solutions | Osmotic Pressure | Freezing Point Depression

Chapter 2 Chemistry Numericals Simplified for Board Exam Success!
This video covers two important numericals from Chapter 2 (Solutions ) for Maharashtra Board Class 12 Chemistry. These questions are crucial for board exam 2025 and are solved with detailed step-by-step explanations to strengthen your understanding of the concepts.
🔑 Numericals Covered:
1️⃣ An aqueous solution of a certain organic
compound has a density of 1.063 gmL-1,
an osmotic pressure of 12.16 atm at 250
C
and a freezing point of -1.030
C. What is
the molar mass of the compound?

2️⃣ A mixture of benzene and toluene contains
30% by mass of toluene. At 300
C, vapour
pressure of pure toluene is 36.7 mm Hg
and that of pure benzene is 118.2 mm Hg.
Assuming that the two liquids form ideal
solutions, calculate the total pressure and
partial pressure of each constituent above
the solution at 300
C.
