How does the number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen?
1 mol of oxygen has fewer molecules.
1 mol of oxygen has more molecules.
Each sample has the same number of molecules.
The molecules cannot be compared without knowing the mass.

Hey there!

Each sample has the same number of molecules.

One mole of a type of molecule is always 6.022 x 10²³ molecules, so no matter what the type of molecule is there will be the same amount of molecules.

The mass, volume, or other properties can be different, but the number of molecules will be the same.

Hope this helps!

Each sample has the same number of molecules.

Explanation:

The difference between them is their mass. It's like a pound of feathers equals a pound of iron they're both a pound.
