Answer from: jinjermaxinejohnston

0.048J/g°C

Explanation:

Given parameters:

Mass of Mercury = 25g

Initial temperature = 25°C

Final temperature = 155°C

Amount of heat absorbed = 455J

Unknown:

Specific heat capacity of mercury = ?

Solution:

To solve this problem, we use the expression below:

Q = m x C x Δt

Q is the heat absorbed

m is the mass

C is the unknown specific heat capacity

Δt is the change in temperature;

455 = 25 x C x (155 - 25)

455 = 25 x C x 130

C = 0.048J/g°C
