Answer: The atomic mass of this element in atomic mass units is 20.3
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
To calculate the number of moles, we use the equation:
Let atomic mass of element is X amu
atoms weigh = X amu
1 atom weigh = 
Atomic mass of this element in atomic mass units is 20.3
