✏️ENEM 2025 PPL | O Brasil produz em média 30 bilhões de litros de etanol por ano. Para cada litro

Brazil produces an average of 30 billion liters of ethanol per year. For every liter of alcohol produced, approximately 10 liters of vinasse are generated, a residue rich in mineral salts and organic matter. This is a detailed explanation of a chemistry question from the 2025 ENEM PPL SECOND APPLICATION exam (yellow version). This is a detailed solution that follows the official answer key.

For each liter of alcohol produced, approximately 10 liters of vinasse are generated, a residue rich in mineral salts and organic matter. This residue can be used to produce microalgae oil for biodiesel manufacturing. For every thousand liters of vinasse, approximately 2.8 L of oil are produced, ready to produce biodiesel. The ratio between the mass of oil consumed and the mass of biodiesel produced is practically 1:1. Consider the density of the oil to be 0.9 kg/L. Available at: https://revistapesquisa.fapesp.br. Accessed on: Dec. 2, 2021 (adapted). If all the vinasse produced annually in Brazil were used in the production of biodiesel, the mass obtained would be closest to: A 3.0 × 10¹¹ kg. B 8.4 × 10⁸ kg. C 7.6 × 10⁸ kg. D 8.4 × 10⁷ kg. E 7.6 × 10⁷ kg. Don't waste time ⌚ subscribe to the channel so you don't miss any content! ❤ ►    / @quimicapravaler   Any questions?
