A sample of tin (Cp = 0.227 J/g•°C) is placed in a freezer. Its temperature decreases from 15.0°C to −10.0°C as it releases 543
J of energy. What is the mass of the sample? Round your answer to three significant figures.
2 answers:
We know, Q = m.c.Δt
m = Q / c.Δt
Here, Q = 543 J
c = 0.227 J/g C
Δt = 15-(-10) = 25 C
Substitute their values,
m = 543 / 0.227 * 25
m = 543 / 5.675
m = 95.68 g
In short, Your Answer would be 95.68 gram
