Answer: The mass of
molecules of phosphorus pentoxide is 20.5 g
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number
of particles.
To calculate the moles, we use the equation:

1 mole of
weigh = 283.9 g
Thus 0.0772 moles of
weigh = 
Thus the mass of
molecules of phosphorus pentoxide is 20.5 g
