The equation for energy of a photon is E=hv where v equals frequency and h equals the Planck constant (6.626X10^-34). So since you've been given frequency you can just plug in frequency to find the total energy in joules.
E=(3.55X10^17)(6.626X10^-34)
E=2.35223X10^-16
Not sure how many significant figures you needed. Hope this helped.
N=14
H= 1(5)= 5
C=12(2)=24
O=16(2)=32
= 75

Sorry if that was useless, I'm not sure how generalized you were being
