Which contains more molecules:

A. 1.00 mol H\(_2\)O\(_2\)
B. 1.00 mol C\(_2\)H\(_6\)
C. 1.00 mol CO

I believe H2O2 has the most, because it also has the most atoms (34) Hope that helps!!

All three given compounds, H 2 ​ O 2 ​ , C 2 ​ H 6 ​ , and CO contain the same number of molecules when comparing equal moles of each, which is Avogadro's number of molecules.
Comparison of Molecule Quantities in 1.00 mol of Different Substances
For any given substance, 1.00 mol will contain Avogadro's number of molecules, which is approximately 6.022 \u00d7 10^2^3 molecules.
This means that whether you have 1.00 mol H 2 ​ O 2 ​ (hydrogen peroxide), 1.00 mol C 2 ​ H 6 ​ (ethane), or 1.00 mol CO (carbon monoxide), each will contain the same number of molecules. Thus, all three options you provided contain the same number of molecules.

All three options contain the same number of molecules, which is 6.022 × 1 0 23 for each 1.00 mol of substance. Therefore, A, B, and C are equal in terms of the number of molecules. No option contains more molecules than the others.
