What is the de Broglie wavelength of a proton that has a mass of 9.11 x 10^-31kg and travels a distance of 13km in 0.025 s? (h=6.63 x 10^-34 Js)

• Chemistry -

wavelength = h/mv
m is in kg.
You will need to change velocity from km/0.025s to m/s.

csaac

• Chemistry -

The answer is 1.57 x 10^2 m/s

• Chemistry -

oops jk wrong one^^^ it's actually 1.4 nm.... sorry
