Answer:
0.478 J/g/C
Explanation:
When solving questions on heat energy, we can use the formula
Q = mcT where
Q is the amount of energy supplied in Joules
m is the mass of the object in Grams
c is the specific heat capacity of the metal in Joules Per Gram Per Degree Celcius
T is the change in Temperature in Degree Celcius.
So by applying the formula to this question, we get:
15000 = (950)(c)(78 -45)
c = 0.478 J/g/C
