We’re being asked to determine the mass of the silver block in the given system.


We will use the heat released by the silver block to calculate its mass. 

Recall that heat can be calculated using the following equation:

q=mcT

q = heat, J

+qabsorbs heat
–qloses heat

 m = mass (g)
 c = specific heat capacity = J/(g·°C)
 ΔT = Tf – Ti = (°C)


Based on the given system:
