It’s Q=mc🔺t and 🔺H=q/mol
The formula for caliometry that you know from AS, just finding out a different value.

Hi,
This is a calculation relating energy change (in Joules) to temperature change (in Kelvin) via specific heat capacity. You'll find this stuff listed under 'Calorimetry' in a text book in the first Energetics section.
The equation is q = mc(delta)T
(I've written 'delta' because that's how it's pronounced; the symbol is a triangle.)
q is energy change in joules (NB, remember to multiply or divide by 1000 if given kilojoules)
m is mass of the water
delta T is the change in temperature in K
