Enthalpy Change in a Calorimeter
Not what you're looking for?
You mix together the following solutions in a coffee-cup calorimeter:
- 100.0 mL of 0.200 M CsOH
- 50.0 mL of 0.400 M HCl
Both solutions start out at 22.50°C, and the final temperature after reaction is
24.28°C. The densities of the solutions are all 1.00 g/mL, and the specific heat of
the mixture is 4.2 J/g°C.
Calculate the enthalpy change (delta H) for this reaction in kJ/mol.

Solution Summary
This solution calculates enthalpy change (delta H) with step-by-step workings. All formulas used are included.
Solution Preview
Conc.(mol/l) = No. of mole/Volume(l)
No. of mole = Conc.(mol/l) x Volume(l)
No. of mole CsOH = 0.200 mol/l x (100/1000)l
= 0.02 mol
No. of mole HCl = .400 ...
