How many moles of the antibiotic tetracycline (C₂₂H₂₄N₂O₈)are in a 50-mg dose? A) 8880 mol B) 22.2 mol C) 8.88 mol D) 0.113 mol E) 1.13 × 10^-4 mol

Question

Quizplus · Accepted Answer

The molecular formula for tetracycline is given as C22H24N2O8. To find the number of moles in a 50-mg dose, first calculate the molar mass of tetracycline. The molar mass is the sum of the atomic masses of all atoms in the molecule: (22 × 12.01 g/mol for C) + (24 × 1.01 g/mol for H) + (2 × 14.01 g/mol for N) + (8 × 16.00 g/mol for O) = 444.44 g/mol. Then, convert the dose from mg to g (50 mg = 0.05 g) and divide by the molar mass: 0.05 g / 444.44 g/mol = 1.13 × 10^-4 mol.
