A 15.5 g piece of chromium, heated to 100.0 degrees Celsius, is dropped into 55.5 g of water at 16.5 degrees Celsius. The final temperature of the metal and the water is 18.9 degrees Celsius. What is the specific heat capacity of chromium

The specific heat capacity of chromium is

Explanation:

As we know that,  

        .................(1)

where,

q = heat absorbed or released

= mass of chromium = 15.5 g

= mass of water = 55.5 g

= final temperature =

= temperature of chromium =

= temperature of water =

= specific heat of chromium= ?

= specific heat of water=

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

The specific heat capacity of chromium is

the answer is b. dilution

that's what i got you can count the number of atoms
