An einstein is the amount of energy needed to dissociate 1 mole of a substance. If we have 0.58 moles, do we need 0.58 einsteins to dissociate that substance?
If the energy absorbed per mole of gas is 480 kJ mol-1, indicate the number of Einsteins per mole.Data: Energy of each photon: 0.7835x10-18 J.
