Sagot :
Answer:
The final temperature of the sample is 21.004 °C
Explanation:
The molar heat capacity for iron is 25.130 J/g.c joules per gram per Kelvin.
What is molar heat capacity?
The amount of heat needed to increase one temperature of one mole of a substance is called molar heat capacity.
By the formula [tex]\rm \Delta T^\circ c = \Delta Tk[/tex]
Given that c = 0.45 J/g.C
Molar mass of iron is 55.845
Then putting the values in the equation
[tex]c= 0.45 \times 55.845 \\\\c= 25.130 \;J/g.^\circ c[/tex]
Thus, the molar heat capacity for iron is 25.130 J/g.c
