AIIMS 2019 Chemistry Raoult's Law MCQ Question

To calculate the number of moles of CHCl₃, we use the formula:

$$\text{Number of moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}$$

Substituting the values for CHCl₃, we have:

$$\text{Number of moles of CHCl₃} = \frac{11.9 \, \text{g}}{119.5 \, \text{g/mol}} \approx 0.0995 \, \text{mol}$$

This calculation confirms that option C is correct. Other options are not applicable as they do not provide relevant information or calculations related to the number of moles of CHCl₃. Understanding this calculation is essential for solving problems involving vapor pressure and colligative properties in solutions.
