Question

What is the wavelength, in nanometers, of light with an energy content of 1898 kJ/mol ?

Express your answer using four significant figures.

Answer 1

The energy of phton can be determined through the formula E= speed of light * Planck's constant divided by the wavelength of light. Placnk's constant is equal to 6.62607004 × 10-34 m2 kg / s while speed of light is equal to 3x10^8 m/s. Hence, the wavelength of light is 1.0465 x10^-22 nanometers.
