Question

Quizplus · Accepted Answer

To find the number of carbon atoms in 10 lbs of sugar, first convert pounds to grams (10 lbs = 4535.92 g). The molar mass of C12H22O11 is 342 g/mol. Calculate moles of sugar: 4535.92 g / 342 g/mol = 13.27 mol. Each mole of sugar contains 12 moles of carbon atoms, so 13.27 mol * 12 = 159.24 mol of carbon atoms. Convert moles to atoms using Avogadro's number (6.022 * 10^23 atoms/mol): 159.24 mol * 6.022 * 10^23 = 9.6 * 10^25 carbon atoms.
