Mercury (ii) sulfide, hgs h g s , contains 86.2\% 86.2 % mercury by mass. the mass of hgs h g s that can be made from 30.0g 30.0 g of mercury is

The question is incomplete. Complete question is attached below.

Correct Option D i.e. 34.8 g

Reason:
Molecular weight of HgS = 232.66 g/mol
Atomic weight of Hg = 200.59 g/mol

Thus, 200.59 g Hg ≡ 232.66 g of HgS
Therefore, 30 g of Hg ≡  = 34.8 g

Thus, 34.8 g HgS would contain 30 g mass percent of Hg
