Does one mole of the antibiotic penicillin G (C 16 H 18 N 2 O 4 S) weigh more or less than one mole of the antibiotic streptomycin (C 21 H 39 N 7 O 12 )?

Streptomycin should weigh more because it has a larger molecular formula, indicating a greater molecular weight compared to penicillin G.

Multiple Choice

Does one mole of the antibiotic penicillin G (C₁₆H₁₈N₂O₄S) weigh more or less than one mole of the antibiotic streptomycin (C₂₁H₃₉N₇O₁₂) ?

A) Actually, they should weigh the same because a mole always has the same mass.
B) Actually, they should weigh the same because a mole always has the same number of particles in it.
C) Streptomycin should weigh more because its individual molecules are larger.
D) Penicillin should weigh more because its individual molecules are larger.
E) It is not possible to determine which one would weigh more because mole size varies.
