a.) What is the photon flux density at P?

b.) What would the photon fluence in one hour?

c.) What is the corresponding energy fluence in SI units?

my work:

a.) 7.5 x 10^8 photons/ (m^2-sec-keV) * (100- 10 keV) = 8.3 x 10^6 photons/(m^2-sec)

b.) 8.3 x 10^6 photons/(m^2-sec) * (3600 sec/hr)= 3.0 x 10^10 photons/m^2

c.) 7.5 x 10^8 photons/ (m^2-sec-keV) * (1 keV/1.602 x 10^-16 J)

= 1.7 x 10^28 photons/(m^2-J)

I have shown my work, but I'm confident with my answers please help!
