Hi i need help with this question

Procedure it attached below, but question is in the screenshot.   Part A: Solution Preparation Work in pairs.  Wear safety goggles and an apron.  Connect the temperature probe to Channel 1 of the LabQuest2. The vertical axis has temperature scaled from 0 to 50°C.  To set the horizontal axis (time) to 0 to 1000 seconds, go to the  menu and change the Duration to 1000 seconds. Wear gloves for this step only, 2.5 M acid can cause burns.  When diluting concentrated acid, pour acid into water, slowly with stirring; never the reverse. HAVE A DILUTION PLAN BEFORE COMING TO LAB.  (Use the concentration values and volume below in the dilution equation to find the volume of stock solution needed to create the dilute solution.)  Using only volumetric glassware, prepare 250.00 mL of approximately 1.0 M HCl solution from the stock HCl solution in the hood (approximately 2.5 M).  The exact concentration for the stock solution must be recorded from the bottle’s label and the exact concentration for…
