a sample of ethanol (c₂h₆o) has a mass of 0.2301 g. complete combustion of this sample causes the temperature of a bomb calorimeter to increase by 1.33°c. the calorimeter has a mass of 2.000 kg and a specific heat of 2.45 j/g·°c. what is the heat of combustion for this sample? kj done

Answer

Explanation:

Step1: Identify the formula

The heat absorbed by the calorimeter $q = mc\Delta T$, where $m$ is the mass, $c$ is the specific - heat capacity, and $\Delta T$ is the change in temperature.

Step2: Convert the mass of the calorimeter to grams

The mass of the calorimeter $m = 2.000\ kg=2000\ g$.

Step3: Substitute the values into the formula

$q=(2000\ g)\times(2.45\ J/g\cdot^{\circ}C)\times(1.33^{\circ}C)$ $q = 2000\times2.45\times1.33\ J$ $q=6417\ J$

Step4: Convert the heat from joules to kilojoules

Since $1\ kJ = 1000\ J$, then $q=\frac{6417\ J}{1000}=6.417\ kJ$

Answer:

$6.417$
