Answer : Option A) the arrangement of bonded atoms.
Explanation : A structural formula of certain molecule depicts the way the atoms are arranged in that particular molecule in any polyatomic species. It helps in deciding the chemical properties of that polyatomic molecule.
Answer:
B. 67.6/Hg(200.5)= .337. 10.8/S(32.1)= .336. 21.6/O(16)= 1.35--> .337/.336= 1 .336/.336= 1 1.35/.336= 4. Formula= HgSO4
