Answer 2

$Energy \: of \: one \: photon \: E = \frac{hc}{ \lambda}$

$Energy \: of \: one \: mole \: of \: photon \: =$

$N_A \frac{hc}{ \lambda}$

$E \: = N_A \frac{hc}{ \lambda}$

$E = N_A \times \frac{6.626 \times {10}^{ - 34} \times 3 \times {10}^{8} }{600 \times {10}^{ - 9} }$

$E = N_A \times \frac{19.878}{5} \times {10}^{ - 19}$

$E = N_ A \times 3.9756 \times 1 {0}^{ - 19} \\ E = 3.97 \times {10}^{ - 19 N_A }$
