Figuring out the Tfinal (see details)?

Question

A 5.00 g sample of aluminum pellets and a 10.00 g sample of iron pellets are placed together in a dry test tube, and the test tube is heated in a boling water bath to 100°C. The mixture of hot iron and aluminum is then poured into 97.3 g of water at 25.5°C. To what final temperature is the water heated by the metals?

how do i figure this out without knowing how much energy was provided?

Answer 1

You need to use the equation E = m c dt

E = energy, c is specific heat capacity, dt is the change in temperature.
Should be fairly simple.
