25.0 g of mercury is heated from 25°C to 155°C, and absorbs 455 joules of heat

in the process. Calculate the specific heat capacity of mercury.

The answer to your question is: Cp = 0.14 J/g°C

Explanation:

Data

mass = 25 g

T1 = 25°C

T2 = 155°C

Q = 455 joules

Cp = ?

Formula

Q = mCpΔT

Clear Cp from the equation Cp = Q / (mΔT)

Cp = 455 / ((25 (155-25))

Cp = 455 / (25 (130))

Cp = 455 / 3250

Cp = 0.14 J/g°C
