In a calorimetry experiment, 100 mL of 0.500 M acetic acid is mixed with 100 mL of 0.500 M sodium hydroxide, resulting in a temperature increase from 25.00 C to 27.55 C. The heat capacity of the calorimeter is 150.48 J/C, and the density of the solution is 1.034 g/mL. The specific heat capacity of 0.250 M sodium acetate is given as 4.034 J/g/C. The calculated enthalpy of neutralization for this reaction is -50.2 kJ/mol. Participants emphasize the importance of demonstrating prior effort in calculations before seeking assistance.

Could I get a solution to this question?

In a laboratory experiment in calorimetry, 100 mL of 0.500 M of acetic acid is mixed with 100 mL of 0.500 M sodium hydroxide in a calorimeter. The temperature rises from 25.00 C to 27.55 C. The heat capacity of the calorimeter is 150.48 J/C, and the density of the resulting solution is 1.034g/mL. Given that the specific heat capacity of 0.250 M of sodium acetate is 4.034 Jg-1C-1, calculate the enthalpy of neutralization of acetic acid.

Answer: -50.2kJ/mol

perhaps you should explain what you've done so far. We don't help you with your homework unless you demonstrate you have at least tried to do it yourself.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
