Three chemistry questions? Deadline tonight..panicking

NOTE: I suppose the procedure is an optional read. Don't read it if you think this question is too long, but please, I beg of you to attempt to help. It is a lab that I've been struggling with for hours.

The Reaction of Sodium Hydroxide Solution with Hydrochloric Acid

Procedure:
1. Measure out approximately 100 mL of 0.50 M hydrochloric acid solution and 100 mL of 0.50 M sodium hydroxide solution. Record both volumes on your data table.
2. Pour the hydrochloric acid solution into the calorimeter. Measure and record the initial temperature of each solution and record on your data table.
3. Add the sodium hydroxide solution to the acid solution in the calorimeter and immediately replace the lid of the calorimeter. Stir the mixture and record the highest temperature reached.

Data & Observations:
Volume of HCl solution: 100.5mL HCl
Volume of NaOH solution: 100.0mL NaOH
Initial temperature in calorimeter: 25.2C
Final temperature in calorimeter: 28.2C

Calculations:
1. (DONE) Write out a balanced equation for the reaction you investigated, including phase symbols.
HCl(aq) + NaOH(s) --> NaCl(aq) + H2O(l)

2. (help?) Determine the enthalpy change of this reaction. The mass of the sodium hydroxide and the mass of the hydrochloric acid should be added together.
3. (help?) Determine the number of moles of NaOH.
4. (help?) Determine enthalpy per mole of NaOH. Show all of your work.

I thank you so much in advance!

2. Q (heat in J)= m (mass of both solutions) C (specific heat of the water) DELTA T(temp change)

3. Moles of NaOH = M x L you have mL so convert to Liters

4. take the Joules you calculated in #2 and divide by the moles you calculated from number 3
