How to calculate the molarity of glacial acetic acid?

Glacial acetic acid is a colorless liquid with a clear appearance. Different companies offer concentrated glacial acetic acid with a purity of 99.7%

( density ) 1 L volume ⟶ ( mass of 1 L solution ) % by mass ⟶ ( mass of solute ) molar mass ⟶ ( number of moles ) 1 L volume ⟶ ( molarity )

The known values are:
The density of glacial acetic acid: 1.049 g / ml
The molecular weight of acetic acid ( CH3COOH ): 60.05 g / mole
The concentration of glacial acetic acid: ( 99.7 % )

Density = Weight Volume
Volume of 100 grams of glacial acetic acid = 1001.049 = 95.329 ml

Its correct so far.
Only
Volume of 100 grams of glacial acetic acid = 1001.049 = 95.329 ml
is strange, what is 1001.049?

100 g correspond to 95,3 ml is correct.
