The heat of fusion of a metal is 7.62 J/g at its freezing point of 592°F. How much energy is required to melt 257 g of this metal (already in 592°F)?

Respuesta :

Answer:

7.62 plug into the equation for freezing

0= 592/7.62x x 90

0 = 77.69x x 90

x=0

therefore according to balton's law, it is required to have 0 + 27.222222222 (balton's number) to get the energy required.

answer is 27.222222 rounded 27. cheers.
