Answer: The molecular formula will be 
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  
The empirical formula is 
The empirical weight of  = 1(12)+3(1)= 15g.
 = 1(12)+3(1)= 15g.
The molecular weight = 45.0 g/mole
Now we have to calculate the molecular formula:

The molecular formula will be=
Thus molecular formula will be

Answer: five cause </h3>
The number of energy levels of zirconium is 5, and I know this because it is located in family five. Families are the rows across on the periodic table. The family number is always equal to the number of energy levels.Zirconium: properties of free atoms. Zirconium atoms have 40 electrons and the shell structure is 2.8.
Hope this helps have a awesome day/night✨
