Because an empirical formula is the simplest form of a compound, we know that the molecular formula contains more atoms than it does. Since we are given the molar mass, we can use this formula.
x ( MM of empirical formula ) = MM of molecular formula
MM of empirical formula = 12(2) + 1(6) + 16 = 46
MM of molecular formula = 138
46x = 138
x= 138 / 46
x=3
Therefore, the molecular formula is 3(C2H6O) that is C6H18O3

What is the empirical formula of a compound with the molecular formula C6H12O6?
CH2O because you have to divide by the number they all have in common which is 6
The empirical formula is CH2O. What is the molecular formula of this compound?
The simplest possibility is the same as the empirical formula, which is the molecular formula of formaldehyde, although it would probably more often be written as H2CO.
Empirical formula for silver oxide?
Silver oxide is an ionic compound so its molecular and empirical formula is same Ag2O
Can the empirical formula of a compound be triple its molecular formula?
No: The molecular formula is never smaller than the empirical formula.
What represent a molecular compound?
This is the chemical formula (empirical formula) or the formula unit of this compound.
Determine the molecular formula for the unknown if the molecular mass is 60.0 amu and the empirical formula is CH2O.?
C2H4O2=molecular formula, basically you multiply the empirical formula by 2.
What is the empirical formula of a compound with the molecular formula C 12 H 8?
Empirical formula: C3H2
How are empirical and molecular for a compound related?
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.

To determine the subscript of an element in a molecular formula the empirical mass must be multiplied by the actual mass?
The actual mass must be divided by the empirical mass. This was derived from the following equation: (subscript)(empirical formula) = (molecular formula) subscript = (molecular formula)/(empirical formula)
