Question

How many oxygen atoms are present in 5.32 moles of CO2

Answer 1

To find the number of oxygen atoms in 5.32 moles of CO2, multiply the moles of CO2 by two (since each CO2 molecule has two oxygen atoms), and then by Avogadro's number to get approximately 6.405 × 10¹²⁴ oxygen atoms.

Step-by-step explanation:

To determine the number of oxygen atoms in 5.32 moles of CO2, we need to consider the molecular composition of carbon dioxide. Each molecule of CO2 contains one carbon atom and two oxygen atoms. Therefore, if you have one mole of CO2, you have one mole of carbon atoms and two moles of oxygen atoms. To calculate the total number of oxygen atoms, you multiply the number of moles of CO2 by the number of oxygen atoms per molecule of CO2, which is two, and then by Avogadro's number (6.022 × 1023 atoms/mole) to get the number of atoms.

Here is the step-by-step calculation:

1. Start with 5.32 moles of CO2.
2. Since 1 mole of CO2 has 2 moles of O, 5.32 moles of CO2 have 5.32 × 2 moles of O, which equals 10.64 moles of O.
3. Now, multiply the moles of oxygen by Avogadro's number: 10.64 moles × 6.022 × 1023 atoms/mole.
4. The result is the number of oxygen atoms: approximately 6.405 × 1024 oxygen atoms in 5.32 moles of CO2.
