Understanding Gram Molecules
To determine the number of gram molecules of oxygen in 6.02 x 10²⁴ molecules of CO (carbon monoxide), we start by analyzing the given information.
Key Concepts
- Avogadro's Number: 6.02 x 10²³ is defined as the number of particles (atoms, molecules) in one mole of a substance.
- Molecular Composition of CO: Each molecule of carbon monoxide (CO) contains one carbon atom and one oxygen atom.
Calculation Steps
1. Identify Molecules of CO: We are given 6.02 x 10²⁴ molecules of CO.
2. Convert Molecules of CO to Moles:
- To find the number of moles of CO, we divide the number of molecules by Avogadro's number:
- Moles of CO = (6.02 x 10²⁴) / (6.02 x 10²³) = 10 moles of CO.
3. Calculate Moles of Oxygen:
- Each mole of CO contains one mole of oxygen. Therefore, if there are 10 moles of CO, there are also 10 moles of oxygen.
4. Convert Moles of Oxygen to Gram Molecules:
- Since 1 mole of any substance is equivalent to 1 gram molecule, we conclude that there are 10 gram molecules of oxygen.
Final Result
- Total Gram Molecules of Oxygen: 10 gram molecules
This systematic approach allows us to understand and calculate the number of gram molecules of oxygen present in 6.02 x 10²⁴ molecules of carbon monoxide effectively.
