Question

The osmotic pressure of an aqueous solution containing 3.42 g of sucrose (C12H22011) in 250 ml solution at 27°C is
0.98 atm
1.51 atm
2.05 atm
2.53 atm​

Answer 1

Answer:

0.98 atm

Explanation:

Osmotic Pressure π=CRT

                              =$\frac{no. of moles}{volume of solution in L}$ × 0.082 × 300

                              =$\frac{3.42/342}{0.250}$ × 24.6

                              =0.04 × 24.6

                              =0.984 atm

                              ≅0.98 atm
