Answer the following questions about the fermentation of glucose (C₆H₁₂O₆ , molar mass 180.2 g/mol) to ethanol (C₂H₆O) and CO₂.

	C₆H₁₂O₆(s)	→	2 C₂H₆O(l)	+	2 CO₂(g)		Δ H = −16 kcal/mol
	glucose		ethanol

How many kilocalories of energy are released from 54.0 g of glucose?

Answer 1

Answer #1

As the equation is balanced, and from here we can see that 1mol of Glucose gives 16Kcal of energy

So 54g of Glucose has 54/180.2 =0.3 moles

Hence 0.3 moles of Glucose will give 0.3×16 =4.8 Kcal of energy

Thank you!
