### De Brogiles wavelength

**Mon Apr 30, 2018 4:06 pm**What is the wavelength of a neon atom traveling with a velocity of 4.34 X 10^3 m/s?

There was a similar question to this on test 2 but I wasn't sure how to do the problem would I convert the moles to atoms then convert grams to kilograms and once I got that it will give me the mass and finally use λ=h/mv in order to find the wavelength is that correct or am I missing something?
