Key Formulas & Calculations
Molarity Formula
M = n / V
Where M = molarity, n = moles of solute, V = volume in liters
Percent by Weight
% w/w = (mass solute / mass solution) × 100
Mass of solute divided by total mass of solution
Parts per Million
ppm = (mg solute / L solution)
Milligrams of solute per liter of solution
Dilution Formula
C₁V₁ = C₂V₂
Initial concentration × volume = final concentration × volume
