A gas cylinder contains exactly 1 mole of oxygen
gas (O2). How many molecules of oxygen are in
the cylinder?
O 4.01 x 1022 molecules
O 6.02 x 1023 molecules
O 9.03 x 1024 molecules
2.89 x 1026 molecules

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules. This implies that 1 mole of oxygen contains 6.02×10²³ molecules.

Since the cylinder contains 1 mole of oxygen, then the number of molecules of oxygen present in the cylinder is 6.02×10²³ molecules.
