Basic chemistry formulas include:

1. Molarity (M): M=nVM = \frac{n}{V}M=Vn​ (moles of solute per liter of solution).
2. Density (ρ): ρ=mVρ = \frac{m}{V}ρ=Vm​ (mass per unit volume).
3. Ideal Gas Law: $PV=nRT$ (relationship between pressure, volume, moles, and temperature of a gas).

The Orchids School provides a complete list of chemistry formulas, which is helpful for students.
