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

it means there are 3 atoms of oxygen

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
