Quizplus · Accepted Answer

de Broglie wavelength, λ = h/p = h/mvwhere h is Planck's constant, p is momentum, m is mass, and v is velocity.Rearranging for velocity, v = h/mλSubstituting the given values, v = (6.626 * 10^-34 J s) / (4.648 * 10^-26 kg * 6.19 * 10^-11 m) = 230 m/s

A Nitrogen Molecule of Mass,m = 4
