A chemist places 1.750 g of ethanol, C2H6O, in a bomb calorimeter with a heat capacity of 12.05 kJ/K. The sample is burned, and the temperature of the calorimeter increases by 4.287 °C. Calculate ΔE for the combustion of ethanol in kJ/mol.
Added by Maria P.
Step 1
Given mass of ethanol = 1.750 g Molar mass of ethanol = 46 g/mol Number of moles of ethanol = Mass/Molar mass Number of moles of ethanol = 1.750 g / 46 g/mol Number of moles of ethanol = 0.038 mol Show more…
