Water i think because it’s a pure substance
The number of molecules of oxygen in the cylinder is 6.02×1023 molecules
Data obtained from the question
Number of mole of oxygen = 1 mole
Number of molecule of oxygen =?
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.
An Arrhenius base is a substance that are being dissolves in water dissociate and gives Hydroxide ions. (OH⁻)
