The molecular formulae is indeed C6H12O6. This is actually a Sugar compound. You are spot on. The molecular formulae is indeed C6H12O6.
This is actually a Sugar compound.

Mass of Element 40 6.6 53.3
Ar 12 1 16
no. of mol 3.33 6.6 3.33
molar ratio 1 2 1

hence empirical formula: CH2O

n
= 180/(12+2+16=30)
=6

therefore molecular formula of Y: C6H12O6
