Question

What is the energy of one mole of photons with a wavelength of 418 nm? (h = 6.63 10-34 J . s, N = 6.02 1023.)

Answer 1

Answer:E = 9.54×10-²Joules

Explanation:

Energy of photon E = hc/¶

Where ¶ is the wavelength

Given h = 6.63×10-³⁴ c= H = 6.02×10²³ ¶ = 418nm = 418 ×10^-9

Substituting the values in the formula

E = 6.63×10-³⁴×6.02×10²³/418 ×10^-9

E = 9.54×10-²Joules
