(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the de Broglie wavelength of an oxygen molecule (molecular mass 32)in air at room temperture.

2. Relevant equations

P = h/ [tex]\lambda[/tex]

P= mv

E= hv = 1/2mv[tex]^{2}[/tex] = P[tex]^{2}[/tex]/(2m)

3. The attempt at a solution

hv = 1/2mv[tex]^{2}[/tex]

h = 1/2mv

If v = P/m then h = mp/2m

so p= 2h

This doesnt seem correct to me... help?
