um depends on the stack
is it a stck of 100, 1000, 50, 25, 44, 38, 57...
if the stack = 100 dollars then theres 50 2 dollar bills
if theres a stack of 100 bills then theres 100 2 dollar bills unless there can be more than one type of bill in the stack and in that case theres even more unlimited possibilities so please be a bit more specific...thanks
