3380 J of heat are added to a 22.2 g sample of iron at 27◦C.?
What is the final temperature
of the iron? The specific heat of iron is
0.449 J/g · K.
Answer in units of K.

This question uses the same equation as the others:
q = m c (T2-T1) where
q is the heat or energy gained or lost
m is the mass of the sample
c is the specific heat in J/gC
T2 is the final temperature and
T1 is the initial temperature
Just plug in the information you are given and solve the equation for what you are trying to find.
(Note: since a change of 1 K = 1 degree C, the specific heat in J/gC or J/gK is the same thing)
Since this asks for the final temperature in K, Just add 273.15 to the value you calculate in degrees C.
