Find delta h for solution of one mole of naoh in h two o
When 2.0 g of NaOH(s) were dissolved in 149g of water in a calorimeter at 24degrees C, the temperature of the solution went up to 29degrees C. If calorimeter constant is 11 cal/deg C, find delta H for the solution of one mole of NaOH in H2O.

The CaC2O4-H2O precipitate is not completely air-dried when its mass is determined. Will the reported mass of the limiting reactant in the original salt mixture be reported too high or too low? Explain.
The temperature of the solution went up to 29degrees C. If calorimeter constant is 11 cal/deg C, find delta H for the solution of one mole of NaOH in H2O.
