Explanation:
Molecular formula
It is the representation of molecule in terms of symbols ,states ,moles etc
. The empirical formula represents the simplest whole-integer ratio of atoms in a compound.
Molecular mass
It is the mass of any molecule .
It is also called as molar mass .
Gram molecular mass
The molecular mass represented in grams becomes : gram molecular mass .
Let us calculate the mass of ammonium hydroxide
It molecular formula is : NH₄OH
The atomic masses of Nitrogen =14 ,hydrogen =1 ,Oxygen is 16.
So, the molar mass is : 14 + 1 x 4 +16 +1 =14+4+16+1=35g
