Answer : Option B) 360 g/mol
Explanation : The antibacterial agent Penicillin N contains 8.92% of sulfur by mass. So we have to calculate the molar mass of penicillin N will be as
i) 256 X 0.0892 = 22.83 g/mol this cannot be the answer as it doesn't shows any sign of sulfur being present even in 1 mole.
ii) 360 X 0.0892 = 32.112 g/mol This is the closest to the molar mass of sulfur which is 32.06 g/mol; this means it contains 1 mole of sulfur.
iii) 390 X 0.0892 = 34.78 g/mol this also fails to prove the answer as correct.
iv) 743 X 0.0892 = 66.27 g/mol This is not even falling in the range of sulfur mole.
Hence we can confirm that the answer is Option B

Answer:
Empirical evidence for a proposition is evidence, i.e. what supports or counters this proposition, that is constituted by or accessible to sense experience or experimental procedure. Empirical evidence is of central importance to the sciences and plays a role in various other fields, like epistemology and law
Protons and neutrons, just like in the nucleus of every other element.
