I discuss the five calculations you need to carry out in order to solve your problem. Be aware that I use different numbers for the mass and ending temperature and I use different heat capacity constants. So, make sure to use your values, not mine!

Donegald... Member since:March 29, 2011Total points:122 (Level 1)I need help with this it is an assignment for uni and cant figure it out. I know I need 15,884 j to heat the water, and that the molar mass of the sodium acetate is 82.03. What enthalpy change do I need, and what is the formula? The assignment is to design a pocket hand warmer, any help would be great.Answer Question by Muppet Member since:June 30, 2010Total points:6,781 (Level 5)What , are you a little terrorist ?
