Answer:Total energy gained by 15.71 g is 3090.6471 joules
Explanation:
Given:
Q = heat gained by the 15.71 gram mass of gold
[tex]Q=mc\Delta T +m\Delta H_{fusion}[/tex]
[tex]\Delta T=(T_{final}-T_{initial})=(1064^oC-32^oC)=1032^oC[/tex]
c = specific heat capacity of gold = 0.1291[tex]joules/gram^oC[/tex]
m = mass of gold =15.71 g
[tex]Q=15.71 g\times 0.1291 joules/gram^oC (1032^oC) +15.71 g\times 63.5 Joules/gram[/tex]
Heat gained by gold = [tex] 2093.0621 Joules + 997.585 Joules[/tex]
=3090.6471 joules
