Answer:
183.3 Km.
Explanation:
- The jet airplane reaches 846 Km in an hour (60.0 min).
- The question is what the distance the airplane covers in 13.0 min.
<em>Using cross multiplication:</em>
846 Km → 60.0 min
??? Km → 13.0 min
∴ The distance that the airplane covers in 13.0 min = (846 Km) (13.0 min) / (60.0 min) = 183.3 Km.

Correct Answer: Option D i.e. 34.8 gReason:
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
