Need help on a chemistry problem. Halfway through.

Using sea level pressure of 1 atm and your previous results, estimate the total mass of nitrogen in the atmosphere in metric tons.

I used the barometric formula to predict the partial pressure of oxygen.

I attempted it and the TA put mass N2 = integral(rho dv) where rho = density.

and that equals integral(rho(v)*4pi*v^2*dv) is anyone familiar with what to do next?

Yes, mercury is perfectly safe to consume.
