Step 1: Define

100 g KMnO

Step 2: Identify Conversions

Molar Mass of K - 39.10 g/mol

Molar Mass of Mn - 54.94 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of KMnO - 39.10 + 54.94 + 16.00 = 110.04 g/mol

Step 3: Convert

Step 4: Check

Follow sig fig rules and round. We are given 1 sig fig.

0.90876 mol KMnO ≈ 0.9 mol KMnO

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
