Stoichiometry And Stoichiometric Calculations

Step 1: Calculate remaining moles
Initial moles = 0.1 mol
Removed moles = 0.01 mol
Remaining moles = mol
Step 2: Convert moles to molecules
Using Avogadro's number ( molecules/mol):
Step 3: Verify calculation

Step 4: Match with options
The calculated value matches option (c).
