Problem

The energy associated with a particular electronic transition in a molecule is

175\,\text{kJ\,mol}^{-1}

. Determine the frequency of a single photon that induces this transition. Express your answer in hertz. (Planck constant

h = 6.626\times10^{-34}\,\text{J\,s}

; Avogadro's number

N_A = 6.022\times10^{23}\,\text{mol}^{-1}

)
