Concentration Calculator

Calculate various types of solution concentrations including molarity, mass percentage, ppm, ppb, and dilutions.

Concentration Types

Choose the type of concentration to calculate

Moles of Solute

Volume of Solution (L)

Mass of Solute (mg)

Total Mass (kg)

Concentration Units

M = moles solute / L solution

Most common for chemical reactions

% = (mass solute / mass solution) × 100

Independent of temperature

PPM = (mass solute / total mass) × 10⁶

Used for very dilute solutions

C₁V₁ = C₂V₂

For preparing dilute solutions
