Moles & Solutions

Moles, molar mass, molarity, dilution and concentration.

• Dilution Calculator (C1V1 = C2V2) Solve C1V1 = C2V2 for any value, with the amount of solvent to add.
• Mass Percent Calculator Mass percent of a solute from its mass and the mass of the solvent.
• Molality Calculator Molality in mol/kg from the mass of solute and the mass of solvent.
• Molar Mass and Molecular Weight Calculator Molar mass and molecular weight from a chemical formula, with the mass percent of each element.
• Molarity Calculator Molarity of a solution from mass and volume, or the mass to weigh out for a target concentration.
• Mole Fraction Calculator Mole fraction and mole percent of each component in a mixture of up to four.
• Moles Calculator Convert between mass, moles and molar mass, with the number of particles.
• Normality Calculator Normality and equivalent weight from mass, volume and equivalents per mole.
• Parts per Million and Parts per Billion Calculator Parts per million and parts per billion from the mass of a substance and the mass of the whole.
• Percentage Concentration Calculator (w/w, w/v, v/v) Percent w/w, w/v or v/v of a solution, or the solute needed to reach a target percentage.
• Solution Concentration Calculator Convert a concentration between mol/L, mmol/L, g/L, mg/L and percent w/v.
