    A student mixed 25.0 cm3 of 2.00 mol dm−3 NaOH with 30.0 cm3 of 1.50 mol dm−3H2SO4 in a plastic cup. The temperature of both solutions was 19.5 °C at the start of the experiment. The maximum temperature was measured as 43.5 °C.
    What is the enthalpy change of neutralisation for this reaction?

    The answer is -55kJ/mol
    but idk how you get to it.

    Thanks
