X-ray photons with a wavelength of 0.135 nm . express the energy numerically in kilojoules per mole.

884.9×10^3 KJ mol-1

Explanation:

From E= hf

E= Energy of the photon

h= Plank's constant

f= frequency of the radiation

But f= c/λ

c= speed of light

λ= wavelength

Hence

E= hc/λ

E= 6.63×10^-34 × 3×10^8/135×10^-12

E= 147×10^-17 × 6.02×10^23

E= 884.9×10^3 KJ mol-1

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

your answers are a,b,,e and f

i hope this
