Question

25.0 g of a substance requires 117.4 Joules of energy to raise its temperature from 75.0 to 87.2 oC. What is the specific heat of the substance?
.054 J/g°C


.063 J/g°C


2.60 J/g°C


.385 J/g°C

Answer 1

Answer:

0.385 J/g°C

Explanation:

c = q/mΔt

c = $\frac{117.4J}{25g * 12.2 C}$ = 0.385 J/g°C

Answer 2

0.385 is your answer
