A 134.0 g sample of an unknown metal is heated to 91.0⁰C and then placed in 125 g of water at 25.0⁰C. The final temperature of the water is measured at 31.0⁰C. Calculate the specific heat capacity of the unknown metal. Specific Heat of water is 4.18 J/g*C pls answer as quickly as possible

Explanation:

Hello,

In this case, since the following equation relates heat, mass, specific heat and temperature:

For the two substances, we say that the heat lost by the metal equals the heat gained by the water, thus we have:

Thus, the specific heat of the metal turns out:

Therefore, we obtain:

Best regards.

catya your not at all which answer i've seen you do this on another question!

i think its 100

i hope this !
