Answer:

The amount of heat require to melt the gold is 1290 J.

Explanation:

Formula:

Q = m × Lf

Q = heat required to melt the substance

m = mass of given substance

Lf = Latent heat of fusion

Given data:

Lf = 64.5 j/g

m = 20 g

Q = ?

Now we will put the values in formula.

Q = m × Lf

Q =  20 g × 64.5 j/g

Q = 1290 J

The amount of heat require to melt the gold is 1290 J.
