For an average molecule of N $2$ gas at $7\mathrm{.}5$ oC$,$ what are its

a$)$ Total Energy?

Number

x$10-21$ J

b$)$ If we make the rough assumption that all this energy is kinetic, what would the momentum of this molecule be$?($Use $14\mathrm{.}01$ g$/$mol for the mass of a N atom$).$

Number

x$10-24$ kg m$/$s

c$)$ What would be the temperature of a He gas atom with the same energy?

Number

oC
