Finding the Temperature at which Oxygen Molecules Have Double the RMS Speed

[Ry122]

Problem:
At what temperature do oxygen molecules have an rms speed that is double their speed at 0 degrees?
Using 1/2mv^2 = 3/2KT I am unable to solve for v since T is 0. Is there another way to do this?

Are you sure it doesn't mean 0 degrees celsius? In that formula, temperature is measured in Kelvin.

i had to convert 0 degrees to kelvin
thanks
