\(100 \mathrm{~mL}\) 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)

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.…
