What is the de Broglie wavelength of an oxygen molecule, O_(2), traveling at 521(m)/(s) ? Is the wavelength much smaller or much larger than the diameter of an atom (on the order of 100pm)?

Calculate the de Broglie wavelength of a Li atom travelling with a velocity of 7.01 x 103 m/s. Give your answer in picometers (1 pm = 1 x10-12 m). Input your answer with 2 decimal places. Do NOT input units. For example, if your answer is 7.931643x10-12 m (which equals 7.931643 pm), enter your answer as 7.93
