Question

calculate osmotic pressure of 0.1m aqueous solution of glucose at 27° c
​

Answer 1

Explanation:

the osmotic pressure of 1m solution at 27" cis 24.6atm

Answer 2

Given:

0.1m aqueous solution of glucose at 27° c.

To Find:

The osmotic pressure of 0.1m aqueous solution of glucose at 27° c.

Solution:

To find the osmotic pressure of 0.1m aqueous solution of glucose at 27° c we will follow the following steps:

As we know,

Osmotic pressure formula = π = iC R T

Here,

i = Vant's Hoff factor = 1, as glucose doesn't dissociate.

π = osmotic pressure

R = universal gas constant = 0.0821 atm mol-1 K-1.

C = concentration of glucose

T = temperature in kelvin = 273 + 27 = 300 K.

Osmotic pressure = 0.1 × 0.0821 × 300 = 2.463 atm.
