Specific Heat Problem in Celsius

[Ki-nana18]

Homework Statement

The specific heat of substance X is 200 J/g*C, how much heat is required to change the temperature of 2.0 kilograms of substance X from 40 degrees Celsius to 55 degrees Celsius?

Homework Equations

Q=(m)(c)(change T)

The Attempt at a Solution

55 C-40 C= 15 C
2.0kg(1000 g/1 kg)= 2000 g

(2000 g)(200 J/g*C)(15 C)= 6000000 J

I'm am not sure if this is right at all. Is it right?
