2. A 5mL container with a hole having a radius of 5106m is filled with hydrogen. This container is placed in an evacuated chamber at 0C. How long will it take for 90% of the hydrogen to effuse out. (Hint: Remember flux () is equal to where A is the area of the hole, N is number of molecules, V is total volume and t is time ) 2.
