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 need the correct calculation to calculate the total enthalpy of the reaction.
