<u>Answer:</u> The uncertainty in the velocity of oxygen molecule is
<u>Explanation:</u>
The diameter of the molecule will be equal to the uncertainty in position.
The equation representing Heisenberg's uncertainty principle follows:
where,
= uncertainty in position = d =
= uncertainty in momentum =
m = mass of oxygen molecule =
h = Planck's constant =
Putting values in above equation, we get:
Hence, the uncertainty in the velocity of oxygen molecule is
