## Concentration to molarity formula

To convert concentration to molarity, you can use the formula

**M = C/M.Wt**

where,

- C = Concentration (mg/mL, ug/L)
- M = Molarity (M or mol/L)
- M.Wt = Molecular weight (g/mol)

## How to calculate concentration to molarity?

To calculate concentration to molarity, Simply Concentration (g/L) divided by the molecular weight (g/mol) then you get molarity (mol/L)

Here step by step

- First, Determine the Concentration (g/L)
- Next, Determine the molecular weight (g/mol)
- Finally, Put values in the above formula

## Solved Example

**Example **– A solution with a concentration of 50 g/L of sodium chloride (NaCl). The molar mass of NaCl is approximately 58.44 g/mol. and calculate molarity

**Given Values-**

- Concentration = 50 g/L
- The molecular weight of NaCl = 58.44 g/mol

Molarity = concentration/molecular weight = 50 / 58.44 = 0.856164 M

the molarity of the solution is 0.856 M
