Final answer:
There are approximately 1.0836 x 10^25 hydrogen atoms in 1.0 mol of penicillin G, as it contains 18 hydrogen atoms per molecule and utilizes Avogadro's number for the calculation.
Step-by-step explanation:
When determining how many atoms of hydrogen are in 1.0 mol of penicillin, it's essential to know the molecular structure of penicillin. Penicillin has multiple forms, but we'll consider benzylpenicillin, also known as penicillin G, with the molecular formula C16H18N2O4SS. This indicates that each molecule of penicillin G contains 18 hydrogen atoms. Since one mole of any substance contains exactly 6.02 × 1023 entities (Avogadro's number), to find the number of hydrogen atoms in 1 mole of penicillin, we would multiply the number of hydrogen atoms per molecule by Avogadro's number:
18 hydrogen atoms/molecule × 6.02 × 1023 molecules/mole = 1.0836 × 1025 hydrogen atoms.
Therefore, there are approximately 1.0836 × 1025 hydrogen atoms in 1.0 mol of penicillin.
