Mole Concept
The number of moles of oxygen atoms in 8.8 g of CO₂ is:
Select the correct option:
Solution
0.4
- Find Moles of CO2:
- Molar mass of CO2=12+2(16)=44 g/mol.
- Moles of CO2=44 g/mol8.8 g=0.2 mol.
- Find Moles of Oxygen Atoms:
- Each molecule of CO2 contains 2 oxygen atoms.
- Total moles of O atoms =Moles of CO2×2
- Total moles =0.2×2=0.4 mol.
