To make a pocket warmer from sodium acetate and vinyl, how do you estimate how many grams to use? to work out the 'q' is it the heat capacity of the water it is dissolved in that you use? What temperature do you want it to get to and how do you factor in the heat capacity of the outer package?

Calculate the enthalpy of hydration, no of moles, amount of sodium acetate to use and over all temperature at the height of the reaction. Please help me with this one? It is all to do with Thermodynamics and Clausis-Clapeyron.
