Asilver block, initially at 59.4 °c, is submerged into 100.0 g of water at 24.8 °c, in an insulated container. the final temperature of the mixture upon reaching thermal equilibrium is 26.2 °c.
what is the mass of the silver block?

The mass of silver block = 73.95 g

Explanation:

Given,

For water:

Mass = 100.0 g

Initial temperature = 24.8 °C

Final temperature = 26.2 °C

Specific heat of water = 4.184 J/g°C

For silver:

Mass = x g

Initial temperature = 59.4 °C

Final temperature = 26.2 °C

Specific heat of water = 0.2386 J/g°C

Heat gain by water = Heat lost by silver

Thus,  

Where, negative sign signifies heat loss

Or,  

So,  

Hence, the mass of silver block = 73.95 g
