Answer:
183.6kg
Explanation:
Given parameters:
Specific heat of the substance = 0.246J/g°C
Change in temperature = 15.5°C
Amount of energy released = 700J
Unknown:
Mass of the sample = ?
Solution:
To solve this problem we used the energy equation:
H = m c Δt
H is the energy released
m is the unknown mass
c is the specific heat
Δt is the change in temperature
Now insert the parameters and find m;
700 = m x 0.246 x 15.5
700 = 3.8m
m = 183.6kg
