Percentage composition by mass: 62.0% Carbon, 10.4% Hydrogen, 27.5% Oxygen. Molar mass is 58.1 g/mol. What is the molecular formula?
--------------------------------------…
62.0/12 = 5.167 for C

10.4/1.008 = 10.317 for H

27.5/16 = 1.719 for O
---------------------------------
taking oxygen as 1, we have:

5.167/1.719 or 3.006 for carbon

10.317/1.719 or 6.002 for hydrogen
---------------------------
and so the empirical formula

for the compound is

C3H6O. But since we are given the

atomic weight of 58.1,

and 12x3 + 6x1 + 16 is 58, then C3H6O

is also the molecular formula.
