For silver, the molar heat capacity(C
p) is equal to 23.43 + 0.00628 T. Calculate the ΔH for the melting of 3 moles of silver from 25°C to 961°C under 1 atm.
From looking through my text, I found this:
ΔH = ΔE + PΔV but at constant pressure it is: ΔH=q
Then to find q(heat): q= mass x Specific heat x ΔT
Being as melting is endothermic process q is positive.
So, would I just plug into what I got? Using 323.61g as its the mass of 3 moles of Ag?
I feel I'm missing something as I've no clue what the molar heat capacity provided is used for.
Any help is appreciated.
