An energy input of

9.0\,\text{kJ}

raises the temperature of

0.30\,\text{kg}

of iron (specific heat

450\,\text{J}\,kg^{-1}\,^{\circ}\text{C}^{-1}

) by

67\,^{\circ}\text{C}

. The same

9.0\,\text{kJ}

of energy is delivered to a sample of aluminum (specific heat

900\,\text{J}\,kg^{-1}\,^{\circ}\text{C}^{-1}

) that starts at the same initial temperature. Determine the mass of aluminum that will experience the same

67\,^{\circ}\text{C}

temperature rise.
