Formulas

Equations

  • Energy of an electron in a Hydrogen like atom
    E = –\frac{2\pi^2me^4Z^2}{n^2h^2}
  • Wavelength of an electron – From DeBroglie’s Equation
    \lambda =\frac{h}{mv} or \lambda =\frac{h}{p} where p is the momentum of the particle
  • Concentration of a solution C expressed in molarity can be calculated using the formula C=\frac{n}{V}
  • The number of moles in a given quantity expressed in grams can be calculated using the following formula n=\frac{m}{Mm} Where ‘m’ is the mass of the substance in grams and Mm is the molar mass of the substance in grams/mole
