31m/s is a typical highway speed for a car. At what temperature do the molecules of nitrogen gas have an rms speed of 31m/s?
T=[(x^2)*m]/3k
so
x=31m/s
m=N2=2*14=28g=.028kg
k=1.38e^23..I'm keep getting 6.333651477e^10...which is incorrect. What am I missing?

Molecules of N2 do not have a mass of .028kg. Perhaps a mole of them have that mass, so divide by avagrado's number for the mass of each.
