Answer:
The correct solution is "[tex]0.480 \ J/g^{\circ}C[/tex]".
Explanation:
Given:
q = 103 J
Mass,
m = 12.6 grams
Temperature,
[tex]T_1=22.4[/tex]
[tex]T_2=39.4[/tex]
[tex]\Delta T=T_2-T_1[/tex]
[tex]=39.4-22.4[/tex]
[tex]=17^{\circ}C[/tex]
Now,
⇒ [tex]C=\frac{q}{m\times \Delta T}[/tex]
⇒ [tex]=\frac{103}{12.6\times 17}[/tex]
⇒ [tex]=\frac{103}{214.2}[/tex]
⇒ [tex]=0.480 \ J/g^{\circ}C[/tex]
