The Medchemexpress Molarity Calculator

Calculate the mass, volume or concentration required for a solution.

The Medchemexpres molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

Mass Concentration Volume Molecular Weight *
= × ×
When preparing stock solutions always use the batch-specific molecular weight of the product found on Datasheet / CoA (available online).
