What osmotic pressure in atmospheres would you expect for a solution of 0.100 M CaCl2 that is separated from pure water by a semipermeable membrane at 310 K? Assume 100% dissociation for CaCl2.

The osmotic pressure is 7.63 atm

Explanation:

We apply the osmotic pressure formula to solve this problem:

π = M . R . T . i

CaCl₂ → Ca²⁺ + 2Cl⁻  (i = 3)

The i refers to the Van't Hoff factor which refers to the amount of ions dissolved.

T is the Absolute T°, for this case 310K

R is the universal constant gase → 0.082 L.atm/mol.K

M is the molarity → 0.1 mol/L

We replace the values → π = 0.1 mol/L . 0.082 L.atm/mol.K . 310K . 3

π = 7.63 atm

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
