Amir Gross · Answer 1

In this case, heat lost is equal to mass times specific heat capacity times change in temperature. We convert the 4.85 kj to a whole number (4850) then multiply the mass (376) by specific heat capactiy (0.128) and then multiply by the overall change in temperature (398-T). We are left with 100.77 being equal to 398 - T, and after finishing the equation, T equals 297.23K.
