100g water, need to raise solution of sodiun acetate 20 degrees. how much energy does it require and how much sodium acetate will you need? Enthalpy of crystallisation is -260kJ. How do I work it out?q= Cp n ∆T? Do you use the density of SA any where? it is 1.528g. I ...

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 ...
