The specific heat of silver is 0.237 J/goC
Its melting point is 961oC . Its heat of fusion is 11 J/g. How much heat (in J) is needed to change 17.5 g of silver from solid at 25oC to liquid at 961oC ?
Add the heat required to warm the silver from room temp to the mp. Then add the heat to melt for the mass of silver. I will be happy to critique your work
