  1. 9V PP3-size battery simply won't be powerful enough, give up on that idea. 4xAA cells perhaps? Best to power the solenoid separately from the Arduino anyhow.
  2. Can't work out what current that solenoid takes, but it will be in 0.2 to 1A range I suspect from the datasheet for the series - you need a power source that can provide this.
  3. circuit and code look basically OK on a quick inspection, MOSFET definitely up for driving that and larger solenoids nicely. Add a 150 ohm resistor between gate and pin6, you don't want to over-current the pin repeatedly, could burn it out.
