Step1: Identify the formula
The formula for heat $Q$ is $Q = mc\Delta T$, where $m$ is the mass, $c$ is the specific - heat capacity, and $\Delta T$ is the change in temperature.
Step2: Determine the values
$m = 180\ g$, $c = 0.900\ J/g^{\circ}C$ (specific heat of aluminum from the table), $\Delta T=T_2 - T_1=50.5^{\circ}C - 16.0^{\circ}C = 34.5^{\circ}C$.
Step3: Calculate the heat
$Q=mc\Delta T=180\ g\times0.900\ J/g^{\circ}C\times34.5^{\circ}C$.
$Q = 180\times0.900\times34.5\ J$.
$Q = 5589\ J$.
