Selected General Chemistry Equations

 Normally general chemistry equations are given to students during exams, so there is no need to memorize them. However, it is important that you know how to used them and when to you them. There are many equations in general chemistry, but are listed below:

Density:

Solution Dilution:

M₁V₁ = M₂V₂

Ideal Gas Law:

PV = nRT

Kinetic Energy:

KE = ½ mv²

Average Kinetic Energy:

KE_avg = ³⁄₂ RT

K_p and K_c

K_p = K_c(RT)^∆n

Einstein’s Energy-Mass Equation

E = mc²

Energy of a Photon:

De Broglie Relation:

Henderson Hasselbalch Equation
