Explanation:

Step1: Recall the relationship between molar - heat capacity and specific heat

The molar mass of silver ($Ag$) is $M = 107.87\ g/mol$. The specific heat ($c$) and molar heat capacity ($C_m$) are related by the formula $C_m = c\times M$.

Step2: Calculate the specific heat

We know that $C_m=25.35\ J\ mol^{- 1}\ ^{\circ}C^{-1}$ and $M = 107.87\ g/mol$. Rearranging the formula $C_m = c\times M$ for $c$, we get $c=\frac{C_m}{M}$.
Substitute the values: $c=\frac{25.35\ J\ mol^{-1}\ ^{\circ}C^{-1}}{107.87\ g/mol}\approx0.235\ J\ g^{-1}\ ^{\circ}C^{-1}$.

Answer:

Value: $0.235$
Units: $J\ g^{-1}\ ^{\circ}C^{-1}$
