3-1 Evaluate Antacids Lab Report Dr Z Edits

I need help with questions 1-4? Also if I'm wrong on question 1 can you do it again? If not you can continue with questions 2-4?

NaOH Concentration (M): 0.09669M   Trial 1: Inital Volume of NaOH: 0.55mL Final Volume of NaOH: 28.25 mL  Trail 2:  Intial Volume of NaOH: 18.1 mL Final Volume of NaOH: 46.1 mL   Concentration of HCl Solution Subtract the initial buret reading from the end point reading. Convert the readings to liters by dividing by 1000.     Solve this equation for the concentration of HCl:                  (CHCl)  (0.01000 liters )    =     (CNaOH)  (volume of NaOH in liters).                CNaOH is the normality of the NaOH you recorded from the bottle.       Average the two HCl concentrations.

I need help with the calculations for this lab.
