Answer 2

Answer:

Dear student,

2 molal solution means 1000g solvent contains 2 moles sucrose.

It means 1000g solvent contains 2x392 = 784g sucrose

Mass of solution = 1784 g.

Volume of solution = 1784/1.4 = 1274 mL

Molarity of solution = 2/1.274 = 1.57 M

Osmotic pressure = CRT

Osmotic pressure = 1.57x0.0821x298 = 40.6 atm

Hope it helps
