Calculate the velocity of an oxygen molecule, given that it has a de Broglie wavelength of 0.0140 nm. A) 890. m.s^-1 B) 3.00 * 10⁸ m.s^-1 C) 1780 m.s^-1 D) 445 m.s^-1 E) 8.90 m.s^-1

Question

Quizplus · Accepted Answer

The de Broglie wavelength formula is λ = h / (mv), where h is Planck's constant (6.626 x 10^-34 Js), m is the mass of the oxygen molecule (approximately 5.32 x 10^-26 kg for O2), and v is the velocity. Solving for v gives v = h / (mλ). Substituting the given wavelength (0.0140 nm = 0.0140 x 10^-9 m) and the known values, the velocity is approximately 890 m.s^-1.
