Some of the most important formulas to memorize for a chemistry test include the Ideal Gas Law (PV = nRT), molarity (M = moles/L), and density (D = m/V). You’ll also need to remember percent composition, dilution (M1V1 = M2V2), and energy calculations (q = mcΔT). Equilibrium constants (Kc and Kp) and pH formulas (pH = -log[H+]) are also crucial. These formulas cover a wide range of typical exam topics. If you’re struggling to keep them straight, consistent practice with problems will help. Many students even search for shortcuts like take my chemistry exam for me when overwhelmed. Instead, focusing on these formulas ensures confidence and success.
