Explanation:

Step1: Identify the formula for heat calculation

The formula for heat released $Q$ is $Q = m\times q$, where $m$ is the mass and $q$ is the heat - of - combustion.

Step2: Substitute the given values

Given $m = 0.511\ g$ and $q=5.71\ kcal/g$. Then $Q=0.511\ g\times5.71\ kcal/g$.

Step3: Calculate the result

$Q = 0.511\times5.71=2.91781\ kcal$.

Answer:

$2.92\ kcal$ (rounded to two decimal places)
