The Solution Concentration Calculator is a multi-functional tool essential for chemists, biologists, and students working in a laboratory setting. It combines three key calculators into one interface: a Molarity Calculator, a Dilution Calculator, and a Concentration Unit Converter.

Molarity Calculator

This tool calculates the molarity of a solution when you know the mass of the solute, its molecular weight, and the total volume of the solution. It uses the fundamental formula:
Molarity (M) = Moles of Solute / Volume of Solution (L)
where Moles = Mass (g) / Molecular Weight (g/mol). It's a quick way to determine the concentration of a solution you've prepared.

Dilution Calculator

Based on the indispensable formula M₁V₁ = M₂V₂, this tool helps you calculate the volumes or concentrations needed to dilute a stock solution to a desired final concentration. You can solve for any of the four variables:

• M₁: Initial Molarity (concentration of the stock solution)
• V₁: Initial Volume (how much stock solution you need)
• M₂: Final Molarity (the desired diluted concentration)
• V₂: Final Volume (the total volume of the diluted solution)

Concentration Converter

This powerful utility converts a known concentration from one unit to many others. You can input a value in Molarity (M), grams per liter (g/L), weight/volume percent (%(w/v)), or parts per million (ppm) and instantly see its equivalent in all other units. This requires the molecular weight of the solute and, for some conversions, the density of the solution.
