Question

What is the osmolarity of a solution created by mixing 3 millimoles of MgCl2 into 1 liter of pure water?

Answer 1

Answer:

The osmolarity of a solution is 0.003

Explanation:

Osmolarity may be defined as the the number of solutes per volume of solution in litres.

The osmolarity of a solution can be calculated as follows:

$Osmolarity=\frac{\text{No. of solute}}{\text{Volume of solution} (l)}$

Here, No. of moles = 3 millimoles= 0.003 moles and volume = 1 liter.

$Osmolarity= \frac{0.003}{1}$

=0.003.

Hence, the osmolarity of a solution is 0.003.
