2% of aqueous urea and 6% of aqueous 'X' are isotonic. If 'X' is a molecular solid, calculate its molar mass.

Text Solution

AI Generated Solution

To solve the problem, we need to find the molar mass of the molecular solid 'X' given that 2% aqueous urea and 6% aqueous 'X' are isotonic. ### Step-by-Step Solution: 1. **Understanding Isotonic Solutions**: - Two solutions are isotonic when they have the same osmotic pressure. The osmotic pressure (π) can be expressed using the formula: \[ \pi = cRT ...
