Question

Can someone check my work please?

Calculate the energy change (q) of the surroundings (water) using the enthalpy equation
qwater = m × c × ΔT.
We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL.
The water has absorbed the heat of the metal. So, qwater = qmetal

Answer 1

Mass of metal = 27.776 g
distilled water = 26 mL
water Temp int. = 25.2 c
metal temp = 100.8 c
mixture = 32.6 c

Answer 2

I got Iron
q = mc(delta T)
=27.776*4.18*(32.6-25.2)
=27.776*4.18*7.4
=859.16
