Q. The osmotic pressure of a 0.01 M solution at 27°C is approximately: (R = 0.0821 L·atm/mol·K)

27°C पर 0.01 M घोल का आसमाटिक दबाव लगभग है: (R = 0.0821 L·atm/mol·K)

A
0.0224 atm
0.0224 एटीएम
B
0.224 atm
0.224 एटीएम
C
2.24 atm
2.24 एटीएम
D
22.4 atm
22.4 एटीएम

Explanation

Osmotic pressure π\pi is given by:

π=cRT\pi = cRT

Where:

  • c=0.01 mol/Lc = 0.01\, \text{mol/L},

  • R=0.0821 L.atm/mol.KR = 0.0821\, \text{L·atm/mol·K},

  • T=27+273=300 KT = 27 + 273 = 300\, K.

Calculate:

π=0.01×0.0821×300=0.2463 atm≈0.224 atm
