Question

calculate osmolarityof water in 0.2M of Alcl3​

Answer 1

Explanation:

osmole (Osmol) is 1 mol of particles that contribute to the osmotic pressure of a solution.

For example,

NaCl

dissociates completely in water to form

Na

+

ions and

Cl

−

ions.

Thus, each mole of

NaCl

becomes two osmoles in solution: one mole of

Na

+

and one mole of

Cl

−

.

A solution of 1 mol/L

NaCl

has an osmolarity of 2 Osmol/L.

A solution of 1 mol/L

CaCl

2

has an osmolarity of 3 Osmol/L (1 mol

Ca

2

+

and 2 mol

Cl

−

)
