An acid-base neutralization reaction causes the temperature of a solution and beaker to rise from 23 degC to 89 degC. The volume of the solution is 435mL. Determine the amount of energy released by this reaction. Assume the specific heat of the solution, which is dilute, is the same as that of water and that the beaker has a heat capacity of 330 J/degC.

Very confused. Any help would be appreciated!

$$ q = m c \Delta T /$$

Right, so when I apply this, where would the mass come from and what do I do with the heat capacity of 330 J/gK of the beaker?

D=m/V

Heat capacity is equivalent of mc - in your case there are two heat sinks, one being solution, the other the beaker.

And mass of the solution can be calculated from volume and density, as Jorriss suggested.
