It takes 945./kJmol to break a nitrogen-nitrogen triple bond. Calculate the maximum wavelength of light for which a nitrogen-nitrogen triple bond could be broken by absorbing a single photon. Round your answer to 3 significant digits.

12.4 * 10^-8 m or 1.24 * 10^--7 m or 124 nm

Explanation:

We have to obtain the energy of the N≡N triple bond in joules as follows;

E = 945 * 1000/6.02 * 10^23 = 9.45 * 10^5/6.02 * 10^23

E = 1.6 * 10^-18 J

But;

E = hc/λ

h = Planks constant

c = speed of light

λ = wavelength of light

λ = hc/E

λ= 6.6 * 10^-34 * 3 * 10^8/1.6 * 10^-18

λ = 12.4 * 10^-8 m or 1.24 * 10^--7 m or  124 nm

the answer is true. hope it .
