Question

Calculate energy of one mole of photons of radiation whose frequency is 5 muntiply 10 14Hz

Answer 1

SoluTion :-

The energy of one photon (E) = hv

$\mathrm {h=6.626 \times 1034 \ js}\\\\\\\mathrm {v=5 \times 10^{14} \ s^{-1}}\\\\\\\mathrm {E=6.626 \times 10^{-34} \times 5 \times 10^{14}}\\\\\\\mathrm {3.313 \times 10^{-19} \ j}$

Energy of one mole of photons = E × A

$\mathrm {=3.313 \times 10^{-19} \ j \times 6.022 \times 10^{-23} mol}\\\\\\\mathrm {=199.50 \times 10^{-3} \ jmol}$
