At 20 C (approximately room temperature) the average velocity of N2 molecules in air is 1050 mph.
What is the velocity of a molecule of N2? What is the kinetic energy of a N2 molecule with this velocity? What is the kinetic energy of a mole of N2?

I know that the velocity is 469.4 m/s^2
and I know that the formula for kinetic energy is 1/2 * m * v^2

However, I cannot get the correct solution for the KE of a N2 molecule or a mole of N2.

    yrtytr

  • Chemistry - ,

    get the weight of N2 into kg
