Answer:
The mass of the silver block is 95.52 grams.
Explanation:
Heat lost by silver will be equal to heat gained by the water

Mass of silver= 
Specific heat capacity of silver = 
Initial temperature of the silver = 
Final temperature of a silver =
=

Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = 




On substituting all values:
we get, 
The mass of the silver block is 95.52 grams.
