A Level enthalpy question
Hey, any help would be much appreciated 
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?

My initial idea was to use q=mcΔT, but I don't know how to work out the numbers to put in?

That's a good start.
You have the temperature change, you have the specific heat constant and you can work out the mass (all of the liquid mixed together)

Oh okay, thank you
