Chemistry Formulas Calculator

1. Ideal Gas Law

PV = nRT

Where P is pressure, V is volume, n is number of moles, R is gas constant, T is temperature

2. Molarity

M = moles of solute / liters of solution

3. pH

pH = -log[H+]

4. Gibbs Free Energy

ΔG = ΔH - TΔS

Where ΔG is Gibbs free energy, ΔH is enthalpy change, T is temperature, ΔS is entropy change

5. Beer-Lambert Law

A = εbc

Where A is absorbance, ε is molar attenuation coefficient, b is path length, c is concentration
