Molar Concentration Formulas
Basic Formula:
Where C = concentration (mol/L), n = moles of solute, V = volume of solution (L)
Unit Conversion:
Where f₁ and f₂ are conversion factors to base unit (M)
Dilution Formula:
For diluting solutions: initial concentration × initial volume = final concentration × final volume
Mass to Molarity:
Where m = mass (g), MW = molecular weight (g/mol), V = volume (L)
