Till it stops.... Hard question to answer accurately... Lotta variables...
The 8-10 oz tank is the most popular for .40 sized models.. Depending on how hard the engine is run AND the type of engine itself, economy will vary.. Typically you'll get 12 - 15 minutes in "normal" flight with a sport engine.. Putting around at 1/4 throttle may get you 20 minutes...
Truly, your mileage may vary....

Till the tank becomes empty. How fast the tank becomes empty would depend on what speed the engine is running, what size prop it is turning, what the mixture is set at, whether it is two or four stroked... Too many variables.
