Answer:
Option B. HgCl2
Explanation:
Data obtained from the question include:
Mass of Mercury (Hg) = 47.3g
Mass of chlorine (Cl) = 16.7g
The empirical formula for the compound can be achieved by doing the following:
Step 1:
Divide by their individual molar mass
Hg = 47.3/201 = 0.235
Cl = 16.7/35.5 = 0.470
Step 2:
Divide by the smallest to express in whole number:
Hg = 0.235/0.235 = 1
Cl = 0.470/0.235 = 2
Therefore, the empirical formula is HgCl2
