Stoichiometry & Solutions

Formulas for mole calculations, molarity, and concentration.

Mole Formula

Where n is moles, m is mass, and M is molar mass.

n = \frac{m}{M}

Molarity

Moles of solute per litre of solution.

C_m = \frac{n}{V}

Mass Percentage

Mass of solute divided by mass of solution.

C_p = \frac{m_s}{m_r} \cdot 100\%

Density

d = \frac{m}{V}

Dilution Law

C_1V_1 = C_2V_2
