$\sim 5 \cdot 10^{18} \ Kg$.

What's the definition of atmospherical pressure ?

Isn't what you're listing the mass, rather than the weight of the atmosphere?

I would be inclined to multiply 19 PSI by the surface area of the earth.

NateTG's right, except that atmospheric pressure is 14.7 PSI.

You mean 14.7 psi, NateTG. I'd be inclined to do the same.

atmospheric pressure is 101325 Pascal. i don't know the wieght.

to many numbers, i think $$10^5 Pa$$ will be good enough.
