A silver block, initially at 56.1 ∘C, is submerged into 100.0 g of water at 24.0 ∘C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 28.0∘C. What is the mass of the silver block?

The mass of the silver block is 256 grams

Explanation:

As we know that,  

        .................(1)

where,

q = heat absorbed or released

= mass of silver = ?

= mass of water = 100.0 g

= final temperature =

= temperature of silver =

= temperature of water =

= specific heat of silver =

= specific heat of water=

Now put all the given values in equation (1), we get

Therefore, the mass of the silver block is 256 grams

is there any options? maybe im just not seeing them but i need the options to
