Calculate molarity, dilutions, and mass-to-moles conversions
Molarity tab: Enter any two of molarity (M), moles (n), or volume (V), and the calculator finds the third. Molarity is the number of moles of solute per liter of solution.
Dilution tab: Uses the dilution equation C1V1 = C2V2. Enter any three values and the fourth is calculated automatically.
Mass to Moles tab: Converts a mass in grams to moles using the molar mass of the substance. Useful for preparing solutions of a specific molarity.
Molarity (M) is a measure of concentration defined as the number of moles of solute dissolved in one liter of solution. It is one of the most common units used in chemistry for expressing solution concentration.
