Review of Calorimetry data collection:

Experimental Data

collected by A. Trenttin (Fall 2020)

Note: some of the following values are estimates...you must use your values that show up in your lab notebook carbon copy.

Reaction 1 - data

NaOH (s) --> NaOH (aq)

- 3.51 g NaOH --> (40.00 g/mol) --> 0.0878 moles NaOH (s)

- ΔT = 34.4 - 22.0 = 12.4 ^oC

Reaction 2 - data

NaOH (s) + HCl (aq) --> NaCl (aq) + H₂O (l)

- 3.43 g NaOH --> (40.00 g/mol) --> 0.0856 moles NaOH (s)

- ΔT = 35.8 - 22.0 = 13.8 ^oC

Reaction 3 - data

NaOH (aq) + HCl (aq) --> NaCl (aq) + H₂O (l)

- 1.76 g NaOH --> (40.00 g/mol) --> 0.0440 moles NaOH (s)

- ΔT = 23.9 - 22.0 = 1.9 ^oC
