\(100 \mathrm{~mL}\) of \(1.5 \%(\mathrm{w} / \mathrm{v})\) solution of urea is found to have an osmotic pressure of \(6.0 \mathrm{~atm}\) and \(100 \mathrm{~mL}\) of \(3.42 \%(w / v)\) solution of cane sugar is found to have an osmotic pressure of \(2.4 \mathrm{~atm}\). If the two solutions are mixed the osmotic pressure of the resulting solution in atm is
(Assume that there is no reaction between urea and cane sugar)
- A 8.4
- B 16.8
- C 4.2
- D 2.1
Answer & Solution
Correct Answer
(C) 4.2
Step-by-step Solution
Detailed explanation
(c) Key Idea Firstly, we calculate the osmotic pressure of each solution by using the formula \(\pi=C R T\) and then, calculate the total osmotic pressure.…
