Unfortunately not correct. See the discussion below...

Explanation:

What you are considering is an interaction between sulfuric acid and the solvent (water). In your equation, you combine two incompatible quantities - the mass of #H_2SO_4# and the heat capacity of water.

While you do not provide the given information for the problem, my hunch is that you are told a mass for the acid, the temperature change of the solution and the amount of water used?

If so, calculate

Q=(mass of water)x(heat capacity of water)x(temperature change)

Then, using the mass of sulfuric acid, determine how many moles have been added.

Divide the value of Q by the number of moles of #H_2SO_4#, and that should give you the result you want.

Note that in doing this, we are assuming the heat capacity of the solution is the same as the heat capacity of pure water.
