Sucrose is fermented by microorganisms into ethanol as seen in the reaction: C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂. In the above balanced chemical equation, how many grams of ethanol are produced from 2.00 moles of sucrose?

Question

Quizplus · Accepted Answer

Based on the balanced chemical equation, 1 mole of sucrose produces 2 moles of ethanol. Therefore, 2.00 moles of sucrose will produce 4.00 moles of ethanol. To convert moles to grams, we need to use the molar mass of ethanol, which is 46.07 g/mol.

4.00 moles x 46.07 g/mol = 184.28 g

Rounding to the nearest tenth gives an answer of 184 g, which is choice B.
