Question

The temperature at which 10% aqueous solution of (W/V) of glucose will show the osmotic pressure of 16.4 atom is (R = 0.082 L atom K-1 mol-1)
(a) 360°C
(b) 180 K
(c) 300 K
(d) 360 K

Answer 1

The correct answer is (d) 360 K.

Explanation:

• We know that the molecular mass of glucose is 180 x  kg.

• While p is 16.4 so using the formula PV = W/M RT.  

• Replacing this with the given values in the question we get 360 K.

• The unit of W/M needs to be used here for specifications.

• This pressure represents the flow of any solvent through a specific material.

Answer 2

The temperature at which 10% aqueous solution of (W/V) of glucose will show the osmotic pressure of 16.4 atom is 360 kelvin .
