You perform an experiment in a coffee cup calorimeter containing 100g of water and the temperature rises from 22.0°C to 44.7°C. How much energy, q, in Joules, is transferred from the reaction into the water (to the nearest whole number)? the specific heat capacity of water is 4.184 J/g.°C q = Cp . m . ΔT ΔT = q / (Cp . m) m = mass of the substance in grams
