The energy is $= 32.27 J$ $=32.27J$

Molecular weight of silver $M = 107.9$ $M=107.9$

Number of moles, $n = \frac{m}{M} = \frac{10.9}{107.9} = 0.101 m o l$ $n=m/M=10.9/107.9=0.101 mol$

Molar heat capagity, $C_m=25.35Jmol^-1ºC^-1$

The change in temperature

$=DeltaT=12.6ºC$

Energy is

$E= n C_m (DeltaT)$

$=0.101*25.35*12.6=32.27J$
