# How can I calculate osmolarity of NaCl?

##### 2 Answers

This is simply twice the molarity of

#### Explanation:

Osmolarity is simply the concentration of all ions in solutions. It is thus the sum of sodium ion and chloride ion concentrations, inasmuch as as sodium chloride is a strong electrolyte, and dissolves to give stoichiometric

You multiply the molarity of the

#### Explanation:

An **osmole** (Osmol) is a mole of particles that contribute to the osmotic pressure of a solution.

For example,

Each ion contributes to the osmotic pressure of the solution.

Thus, each mole of

A solution of 1 mol/L

**EXAMPLE**

Calculate the osmolarity of 0.140 mol/L

**Solution**

Each mole of

∴
