Enthalpies of Formation (Section)
The heat of combustion of ethanol, C2H5OH(l), is –1367 kJ/mol. A batch of Sauvignon Blanc wine contains 10.6% ethanol by mass. Assuming the density of the wine to be 1.0 g/mL, what is the caloric content due to the alcohol (ethanol) in a 6-oz glass of wine (177 mL)?
Step 1 of 4
The heat released by a substance during its combustion is referred to as its calorific value.
The heat of combustion of ethanol is .
The percent by mass of ethanol is 10.6 %.
The density of wine is 1.0 g/mL.
The volume of wine is 177 mL.
