Answer: The number of molecules in 1 mol of oxygen are equal to the number of molecules in 1 mol of nitrogen.
Step-by-step explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number
of particles.
1 mole of oxygen
contains =
molecules of oxygen
1 mole of nitrogen
contains =
molecules of nitrogen
Thus number of molecules in 1 mol of oxygen are equal to the number of molecules in 1 mol of nitrogen.
