Question about Solenoid

How many shots does a full tank of 100psi with one solenoid have?

From any of the Pneumatics Kit product pages:

Or, from the Bots ā€˜nā€™ Stuff Wiki:
(Single-acting solenoids are on/off because of the spring-return in the single-acting cylinders. Therefore it only takes air to push the cylinder out, allowing double the number of strokes.)
