Specific Heat (kCal and J) for copper, help please

[strayaway]

Homework Statement

How much heat is required to raise the temperature of a 50 gram cube of copper from 20 degrees Celsius to 45 degrees Celsius? (in kcal and J)
Specific Heat(20degrees Celsius) for Copper (kcal/kg x degrees Celsius) is 0.092. and the Specific Heat for Copper (J/kg x degrees Celsius) is 385.

Homework Equations

H = mc (triangle) T

The Attempt at a Solution

so the first thing I did was convert the 50 grams to 0.05 kg, then I set up the equation by putting "H = 0.05kg x 20degrees x 25 degrees. but then that's where i got stuck because I didn't know how to incorporate the specific heat into this.

I highlighted a couple of items in your post; the thing you wanted to calculate.

You know m - you even converted it to kg; good.
You know C [you were given its value in 2 unit systems, I would be using the SI unit value to find Joules.
You know delta T [20 to 45 equals a change of ...]

Substitute and calculate.
