    Your question is not complete. Could you re-post it please?

    And while you're at it, post also your attempt at solving the problem.

    Maybe you'll need to use this formula:

    Where Q is the energy involved,
    m the volume or mass of water,
    c the specific heat capacity of water,
    and theta the change in temperature.

How do I find the enthalpy change in a calorimeter? [ 1 Answers ]

A calorimeter contains 30.0 mL of water at 12.0 C. When 1.60 g of X (a substance with a molar mass of 45.0 g/mol) is added, it dissolves via the reaction X (s) + H2O (l) → X (aq) and the temperature of the solution increases to 28.5 C. Calculate the enthalpy change, Delta H, for this...

Heat capacity of a calorimeter [ 4 Answers ]

Assume you are performing the calibration step of Experiment 8 and you begin with 50 g of water at 20 C and 50 g of water at 80 C. After adding the two portions of water into your calorimeter setup and following the procedure outlined in the experiment, you determine the temperature of the mixed...
