What is the energy content in joules of a 1.28g sample of oatmeal that raises the temperature of 1.50 kg of water in a calorimeter from 25.0 c to 27 c

12560 J.

Explanation:

The amount of heat absorbed by water = Q = m.c.ΔT.

where, m is the mass of water (m = 1.5 kg = 1500.0 g).

c is the specific heat capacity of water = 4.186 J/g°C.

ΔT is the temperature difference = (final T - initial T = 27°C - 25°C = 2°C).

∴ The amount of heat absorbed by water = Q = m.c.ΔT = (1500.0 g)(4.186 J/g°C)(2°C) = 12560 J.

what is the question here. i think you messed up.
