1375 J of heat energy are added to a 50.0 g sample of copper, which increases temperature from 22.8 C to 94.2 C. Calculate the specific heat of copper.

Respuesta :

Answer:

0.385 J/G ° C

Explanation:

Q = mcΔT

Q = 1375 J

m = 50.0 g

c = Unknown

ΔT = 94.2 C - 22.8 C = 71.4 C

1375 J = (50.0 g)(x)(71.4 C)

1375 J = (3570 g/C)(x)

0.385154062 J/G ° C = x

Recall your answer must have 3 significant figures

x = 0.385 J/G ° C
