is this the correct answer?

Question

E = hv

h= 6.626 x 10^-34 J s

Ultraviolet radiation has a frequency of 6.8 × 10^15 1/s. Calculate the energy, in joules, of the photon.

E=6.626 x 10-34 J s X 6.8 x 1015 1/s

E =45.0568 x 1/1019 J s

Answer 1

Working with the same numbers, I get

E = 4.50568 x 10^-18 J

which is the same as 45.0568 x 10^-19 J (i.e. the same as your answer)
