Question

A solution of sucrose are dissolving 68.4 g per litre of solution what is its atmospheric pressure at 300 k

Answer 1

Answer:

The osmotic pressure of the solution is 4.195 atm.

Explanation:

Mass of sucrose = 68.4 g

Moles of sucrose in 1 L of water = $\frac{68.4 g}{342.3 g/mol}=0.1998 mol$

Temperature of the solution = 300 K

Osmotic pressure = $\pi=cRT$

$\pi=0.1998 mol/L\times 0.0820 atm l/L K\times 300K =4.915 atm$

The osmotic pressure of the solution is 4.195 atm.

Answer 2

Answer:

answer is 4.92 atmospheric
