The energy of a single photon is 2.038x10^-18 J. What is the energy of one mole of these photons, in kilojoules?

science chemistry

Answer 1

Answer #1

Energy of one mole = Energy of one photon*Avogadro no.

= ( 2.038×10^-18)(6.022×10²³)

( Avogadro no.=6.022×10²³ /mol)

= 12.27×10⁵ j/mol

. = 12.27×10⁵×10^-3(1j=10^-3 kj)

Energy of one mole = 12.27×10² kj/mol

Energy of one mole = 1227 kj/mol
