Please show me how to do a question like this.

Answer 1

In this question, we can use the Calorimetry formula in order to find this answer, the formula for Calorimetry is:

Q = mcΔT

We have:

Q = 10000 J

m = ?

c = 0.39 J/g°C

ΔT = 225 - 100 = 125°C

Now we add these values into the formula:

10000 = m * 0.39 * 125

10000 = 48.75m

m = 205 grams of Copper
