All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.

A molecule contains 47.30 g mercury (Hg) and 16.70 (Cl). what is its empirical formula?

Bogdan [553]

Answer: B) HgCl2

Explanation:

Convert grams to moles for both elements by dividing the mass by it’s molar mass (Mr).
Hg- 47.30/201= 0.23 mols
Cl- 16.70/35= 0.47 mols

Now, divide the moles of both elements with the smallest number. The smallest number here is 0.23.
Hg- 0.23/0.23= 1
Cl- 0.47/0.23= 2.04 (since there is a 0 after the decimal we will forget the decimal and write the number as a whole.)

Empirical Formula= Hg1Cl2
