When a 5.00 g sample of NaOH dissolves in 100.0 g of water in a "coffee cup" calorimeter, the temperature rises from 28.3 degrees C to 39.6 degrees C. Calculate the heat energy for the reaction of 5.00 g of NaOH AND the heat of solution (reaction) for one mole of NaOH dissolving in water.
Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
