Full Answer

The unit abbreviations listed on the AP Chemistry formula sheet include those for liters, milliliters, grams, nanometers, atmospheres, joules, volts and moles. In the atomic structure section of the formula sheet, the values are given for Planck's constant, the speed of light, Avogadro's number and the electron charge. Formulas provided in that section include E = hv and c = wavelength * v; E represents energy, v represents the wavelength, h represents Planck's constant and c represents the speed of light.

Constants listed under the equilibrium section include those for molar concentration, gas pressure, weak acid, weak base and water. The formula for determining the pH of an acid or base is also listed. The kinetics section includes the formula for half-life decay, along with constants k for the rate constant and t for time. The section on gases, liquids and solutions gives the formula D = m/V, where D is density, m is mass and v is volume. The thermochemistry and electrochemistry section includes formulas on heat, entropy and enthalpy.
