leaking air??

Homework Statement



Suppose we make a circular hole 3 millimeter in diameter in a balloon. Calculate the initial rate at which oxygen escapes through the hole (at 0° C), in number of oxygen atoms leaving the balloon per second.


Homework Equations



i used 1/4 nAv where n = number of molecules / Volume


i did not know the n or the v for this problem so did not attempt it completely :(

Isn't there any dependence on the pressure differential across the leak hole?

I am having trouble with this problem as well. Using that equation I only know that A=(pi*3^2) but don't know how to get v or how to solve for the rate of leakage (atoms per second). Any help would be appreciated.
