What is the average de broglie wavelength of oxygen molecules in air at a temperature of 27°c? use the results of the kinetic theory of gases the mass of an oxygen molecule is 5.31 x 1026 kg

Explanation:

Average velocity of oxygen molecule at given temperature is

now we have

M = 32 g/mol = 0.032 kg/mol

T = 27 degree C = 300 K

now we have

now for de Broglie wavelength we know that

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)

explanation:
