Answer:

$m_{Ag} = 175.987\,g$

Explanation:

The First Law of Thermodynamics helps to determine the mass of the silver block:

$m_{Ag}\cdot \left(0.235\,\frac{J}{g\cdot ^{\textdegree}C} \right)\cdot (55.6^{\textdegree}-27.3^{\textdegree}C) = (100\,g)\cdot \left(4.18\,\frac{J}{g\cdot ^{\textdegree}C} \right)\cdot (27.3^{\textdegree}C-24.5^{\textdegree}C)$

The mass of the silver block is:

$m_{Ag} = 175.987\,g$
