Concentration to Molarity (M) Calculator

Formula

The formula to convert concentration from mg/ml to molarity is:

\[ M = \frac{C}{MW} \times 1000 \]

Where:

\( M \) is the molarity (M)
\( C \) is the concentration in mg/ml
\( MW \) is the molecular weight in g/mol

What is Molarity?

Molarity, denoted as M, is a measure of the concentration of a solute in a solution. It is defined as the number of moles of solute per liter of solution. Molarity is one of the most common units used to measure the concentration of a solution in chemistry.

Example Calculation

Let's assume the following values:

Concentration (C): 50 mg/ml
Molecular Weight (MW): 180 g/mol

Step 1: Calculate the Molarity:

\[ M = \frac{50}{180} \times 1000 = 0.2778 \text{ M} \]

Therefore, the molarity is approximately 0.2778 M.
