Question

What is the osmotic pressure of the solution
obtained by mixing 300 cm3 of 0.6%
(mass-volume) solution of urea with 300 cm3
3.42% solution of sucrose of 20°C ?
(1) 5 atm (2) 5.2 atm (3) 2.4 atm (4) 4.5 atm​

Answer 1

Explanation:

1. moles of urea=(0.6×3)÷60=1.8
2. concentration=moles÷volume=1.8÷0.3=6
3. similarly conc. sucrose.....
4. osmotic pressure=CRT
