Answer
0.24 joules
Work Step by Step
From the given question, we know
Heat capacity of the chunk of silver = 42.8 J/c
Mass of the silver = 181 g
Now we also know the formula for determining the specific heat of silver and that is
Specific heat (C) = heat capacity/ mass
= (42.8/181) J/gC
= 0.24 J/gC
So the specific heat of the silver is 0.24 J/gC.
With the given known facts, it is easily possible to find out the specific gravity of any substance.
