The number of mole of ethanol present in the sample is 0.005 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation
Mole = mass / molar mass
With the above formula, we can obtain the mole of ethanol
<h3>How to determine the mole of ethanol</h3>
- Mass of ethanol = 0.2301 g
- Molar mass of ethanol = 46 g/mol
- Mole of ethanol = ?
Mole = mass / molar mass
Mole of ethanol = 0.2301 / 46
Mole of ethanol = 0.005 mole
Complete question
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. How many moles of ethanol are present in the sample?
