If 46.1 g zn at 18.0 c is placed in 80.0 g h2o at 75.0 c, what is the final temperature of the mixture? the specific heat capacities of zinc and water are 0.388 j/g·k and 4.184 j/g·k, respectively

Answer : The final temperature of the mixture is, 345.108 K

Explanation :

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

where,

= specific heat of zinc =

= specific heat of water =

= mass of zinc = 46.1 g

= mass of water = 80.0 g

= final temperature of mixture = ?

= initial temperature of zinc =

= initial temperature of water =

Now put all the given values in the above formula, we get:

Therefore, the final temperature of the mixture is, 345.108 K
