Answer:1600 cal

Explanation:The formula

q=mΔ[tex]H^{0}[/tex]

is used to calculate the heat required to melt a solid where q=amount of heat, m=mass and Δ[tex]H^{0}[/tex] is the enthalphy of fusion

now we substitute, m=20g, Δ[tex]H^{0}[/tex]=80cal/g

Therefore, q=20g x 80cal/g =1600 calI hope you find this information useful and interesting! Good luck!
