How much heat is added to 10 g of water when you start from room temperature and heat it to its boiling point?

We need to find the specific heat capacity of water. This can be found in google or textbooks.
specific heat of water = 4.184 J/g-K
Then we use the formula
Q = m*c*(T2 - T1)
where
Q = energy (J)
m = mass (g)
c = specific heat capacity (J/g-K)
T = temperature
I'm not sure about the room temperature. Some references say it's 25 deg C, while some say it's 20 deg C. But anyway, I'll just use 25 deg C.
The boiling point of water is 100 deg C.
Substituting,
Q = 10 * 4.184 * (100 - 25)
Q = ?
