Third Attempt - Last Try!!! HELP!!! Please help with the Chemistry Lab problem

on Titration and Vinegar? After transferring a 10.00mL sample of HCl solution into a 125mL Erlenmeyer flask, 50mL of distilled water and 3 drops of phenolphthalein was added. The resulting solution requires 44.00mL of 0.1250M NaOH solution to reach the end point.
1. Calculate the number of moles of NaOH required for titration.
2. Calculate the number of moles of HCl in the HCl smaple titrated.
3. Calculate the molarity of HCl.
