Calculate energy required (in kJ) to convert 225g water at 21 degrees C to steam at 115 degrees C

It would be awesome if you could show any formulas used, as I really need to know them.
It would really, really be appreciated if you could help. Thanks!

Calculate the energy required (in kJ) to convert 225 grams of liquid water at 21 degrees celcius to steam at 115 degrees celcius.

It also has these hints: Heat of fusion = 333 J/g, heat of vaporization = 2256 J/g.
Specific heat capacity of water = 4.184 J/gK
Specific heat capacity of steam = 1.92 J/gK

Three equations are required:

1) heat water from 21 to 100 ( use 4.184)
2) boil water at 100 (use 2256)
3) heat steam from 100 to 115 (use 1.92)

Here are the numbers:

q1 = (225) (79) (4.184)
q2 = (225) (2256)
q3 = (225) (15) (1.92)

Your final answer is this:

q1 + q2 + q3
