Suppose you did the dissolution of NaCl(s) experiment again and found that for a 0.837 M solution of NaCl(aq) with a mass of 104.8 g, the temperature of the solution went from 23.23 °C to 22.90 °C (i.e. ΔT = -0.33 °C). Use the equations below to find ΔHdiss.

Based on the appearance of the pH vs titrant volume plot, the titrant is a(n) [ansA] and the analyte is a(n) [ansB].  

Consider the substances A, B and C and their molar conductivities shown in the table below. Substance Molar conductivity (S/mol) A 92.4 B 0.331 C 0.00 What can be said about these substances?

What is the name of the piece of glassware shown below?  

Suppose you measured the per gram ΔHdiss of NaCl(s) to be 6.54 × 10-2 J g-1. If the generally accepted value is 6.67 × 10-2 J g-1, what is your percent error?
