a)
[tex]\Delta U=1,5nkT[/tex]

finn stoffmengden (n) for O2(g) og He(g)
T = 373 K
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
b)
[tex]\bar v(O_2) = \sqrt{\frac{3RT}{M}}=\sqrt{\frac{3RT}{0,032}}[/tex]

[tex]\bar v(O_2) \approx 539\,(m/s)[/tex]

u.s.w.

Takk for svaret, men vet du hvordan jeg kan løse oppgave d?

se på
[tex]\bar v(mixture) = \sqrt{0.5(v(O_2)^2 + v(He)^2)}[/tex]
