Three Introductory Chemistry students each measured 50.0 mL of 1.0 M NaOH into "double-walled" styrofoam cup calorimeters. Then, Sue added 50.0 mL of 1.1 M HCl to her NaOH solution; Karel added 45.5 mL of 1.1 M HCl to his; and Caleb added 50.0 mL of 1.0 M HCl. Two of these students will report, within experimental error, the same increase in solution temperature for the neutralization. Which are the two students? Explain.
