Answer:
molecular formula = C₃H₆O₃
Explanation:
The empirical formula is the simplest formula of a compound obtained by converting the moles of each atom to the simplest ratio.
In order to determine the molecular formula we will first calculate the empirical formula mass of compound.
Empirical formula mass = mass of C + 2 X mass of hydrogen + mass of O
Empirical formula mass = 12 + 2 +16 = 30
given molecular mass = 90.087
Let us divide the molecular mass by Empirical formula mass
ratio = 90.087 / 30 = 3 (approx)
Thus the molecular formula = 3 X empirical formula of compound
molecular formula = 3 (CH₂O)
molecular formula = C₃H₆O₃
