Answer:

27.03 g/mol

Explanation:

Molar Mass of HCN

Mass of Hydrogen : 1.008

Mass of Carbon: 12.01

Mass of Nitrogen: 14.01

Molar Mass of HCN =

1.008 + 12.01 + 14.01=

27.03 g/mol

The equation for photon energy, E, is E=hc/λ
Leni [432]

Answer:

The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m

Explanation:

The wavelength is defined for every periodic wave, that is, for the type of wave that repeats itself with exactly the same shape every given interval of time. It is the distance between two points from which the wave repeats.

Radiation is the emission, propagation and transfer of energy in any medium in the form of electromagnetic waves or particles.

The energy carried by electromagnetic radiation travels by waves. This energy is transmitted grouped in small "quanta" of energy called photons. The energy of a photon is measured in Joules (J) and is

E=\frac{h*c}{wavelength}

Being:

  • E=3.92×10⁻¹⁹ J
  • h= 6.626×10⁻³⁴ J⋅s (Planck's constant)
  • c = 2.99×10⁸ m/s (the speed of light)
  • wavelength=?

and replacing:

3.92*10^{-19}J =\frac{6.626*10^{-34}J.s*2.99*10^{8}\frac{m}{s}   }{wavelength}

you get:

wavelength =\frac{6.626*10^{-34}J.s*2.99*10^{8}\frac{m}{s}   }{3.92*10^{-19}J}

wavelength= 5.054*10⁻⁷ m

<u><em>The wavelength, λ, of a photon that has an energy of E = 3.92×10⁻¹⁹ J is 5.054*10⁻⁷ m</em></u>
