calculate the average volume of sodium hydroxide required for the titration of 25.00mL of the standard sulfuric acid solution.
From my data i have trial 1 and 2 to be 19.80ml and 19.80ml of NaOH used so do i just add them and divide it by two to get the average?

Yes, but if both volumes are 19.80 mL you know the average will be 19.80.

How do I type I2 meaning Iodine

I2 is elemental iodine.
If you REALLY want to go the to trouble you can write it as I_{2} but that takes too much time and everyone who uses this forum understands that I2 means I with a subscript 2.
