Answer: The object's heat of fusion is 68.52 Joules/gram.

Explanation:

Mass of the sample = 42 grams

Energy required to melt the sample completely = 2878 Joules

$Q=m\times\Delta H_{fusion}$

$2878 Joules=42\times \Delta H_{fusion}$

$\Delta H_{fusion}=\frac{2878 Joules}{42 g}=68.52 Joules/gram$

The object's heat of fusion is 68.52 Joules/gram.
