How many CO2 molecules can be made with 0.500 mol of oxygen atoms?
0.5 mol O atoms can make 0.5/2 moles CO2 molecules. Then 0.25 moles x 6.022E23 = #molecules.
I don't understand how to work this problem can you help

To determine how many CO2 molecules can be made with 0.500 mol of oxygen atoms, we need to consider the balanced chemical equation for the formation of carbon dioxide (CO2) from oxygen (O2):
2 O2 + C → 2 CO2
From this equation, we can see that it takes 2 molecules of O2 to produce 2 molecules of CO2.
Given that we have 0.500 mol of oxygen atoms, we need to convert this quantity into the number of molecules it represents. To do this, we use Avogadro's number, which states that 1 mole of any substance contains 6.022 × 10^23 particles (atoms, molecules, ions, etc.).
Thus, the number of molecules of oxygen can be calculated as follows:
Number of molecules of oxygen = 0.500 mol × (6.022 × 10^23 molecules/mol)
Now, since it takes 2 molecules of O2 to produce 2 molecules of CO2, the number of CO2 molecules that can be made will be the same as the number of O2 molecules.
Therefore, the number of CO2 molecules that can be formed with 0.500 mol of oxygen atoms is:
Number of CO2 molecules = 0.500 mol × (6.022 × 10^23 molecules/mol)
To obtain the numerical value, we can perform the calculation.
