Molarity Calculator allows you to calculate any of mass, volume, and the molar concentration.

Built-in unit converter makes it a snap to calculate molarity from any mass or volume units.

Simply pick the calculation you want to perform, enter your values, and pick the units.

This is a general purpose molarity calculator that will calculate the mass of reagent needed to make a particular concentration of solution. It can solve for reagent mass, solution volume, and molar concentration given the other two parameters (and the formula weight).
