Question

The relationship between the osmotic pressure at 273 kelvin when 10 gram glucose even 10 gram usia p2 and

Answer 1

Temperature = 273 K

Mass of glucose = 10g

Mass of urea = 10g

Mass of sucrose = 10g

Volume of solvent (water) = 250 ml

Molar mass of glucose = 180.156 g/mole

Molar mass of urea = 60.06 g/mole

Molar mass of sucrose = 342.296 g/mole

where,

= osmotic pressure

w = given mass

R = gas constant

T = temperature

M = molar mass

V = volume of solvent

From the formula, we conclude that the Osmotic pressure is inversely proportional to the Molar mass, since other values are same for all three compounds.

Osmotic pressure of glucose, urea and sucrose is represented as ,  and  respectively.

This means that the lower the molar mass of the compound, the higher will be the osmotic pressure of compound.

So, the relationship between the osmotic pressure of glucose, urea and sucrose is,
