m=1.66 v=5.00 h=6.63

(6.63)/ (1.66 x 5.00) = 6.63/8.3=0.79

My answer is 0.79 E-34 m. Is this correct?

What you have, I think, is that

planck'sconstant=wavelength*mass*velocity

Where did you get that?

Most of us use this:

Energy= h*c/lambda where c is the velocity of light, and lambda is wavelength.
