Question

if the molar concentration of the given sugar solution is 0.3 M find out the osmotic pressure of this solution
1. 6.72atm
2. 67.2atm
3. 2.24atm
4. 5.60


And is 1. 6.72atm

Answer 1

Explanation:

The molar concentration of the given sugar solution is 0.3 M find out the osmotic pressure of this solution

1. 6.72atm is the answer

Answer 2

The complete question is molar concentration of sugar solution is 0.3M find out the osmotic pressure of this solution at absolute temperature?

We know that osmotic pressure of a given solution is given by p=MRT

where p is osmotic pressure of solution

M is the molarity or concentration of solution =0.3M

R is universal gas constant whose value is 0.082 L atm /mole K

T is absolute temperature =273 K

Substituting the values we have:--

p=0.3*0.082*273 atm

p=1.672 atm

Hence osmotic pressure of 0.3M solution at absolute temperature is 1.672 atm.
