Empirical formula = C3H5O
Molar mass of empirical formula = 3(12.01)+5(1.008)+1(16) = 57.07
Molar mass of molecular fomula = 114.15
n = Molar mass of molecular fomula/Molar mass of empirical formula
= 114.15/57.07
n = 2
Molecular formula = n(empirical formula)
Molecular formula = 2(C3H5O) = C6H10O2
Check:
6(12.01)+10(1.008)+2(16)= 114.14

The combustion data for an unknown compound containing carbon hydrogen and oxygen was analyzed and the empirical formula for the unknown was found to be C3H5O The molar mass of the unknown was found?
C6h12o3
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.
An unknown sample with a molecular mass of 180.0g is analyzed to yield 40 percent C 6.7 percent H and 53.3 percent O What is the empirical formula and the molecular formula of this compound?
ch2o and c6h12o6
What is HRMS weight?
High resolution mass spectrometry weight. It is used to narrow down the molecular formula of an unknown molecule.
What is the molecular formula for the unknown C2H4O?
That is a molecular formula.I can't off the top of my head think of any compound with that molecular formula, though. It's not methoxyethane or a propanol, because it's got one too few hydrogen atoms. It's not propanone or cyclopropanol or oxetane or a propenol, because it's got one too many hydrogen atoms.
Which chemical formula is both an empirical formula and a molecular formula?
It would be a molecular formula for C3h5o.
What is the empirical formula C12H6O3?
The principle for this kind of problem is to find the highest integer that is an integral factor of all the subscripts, then divide the subscripts by that integer. In this instance, 3 is the highest integer, since 15/3 = 5, a prime number, and 5 is not an integral factor of 9 or 3. Therefore, the empirical formula would be C3H5O.

What is the empirical formula for C9H15O3?
A molecular formula is identical to the empirical formula. The principle for this kind of problem is to find the highest integer that is an integral factor of all the subscripts then divide the subscripts by that integer. In this instance 3 is the highest integer. Therefore the empirical formula would be C3H5O.
How does one determine a molecular formula from the empirical form?
molar mass of unknown/molar mass of empirial = # of empirical units in the molecular formula. Example: empirical formula is CH2O with a molar mass of 30. If the molar mass of the unknown is 180, then 180/30 = 6 and molecular formula will be C6H12O6

If an unknown hydrate MgCl2 and bullxH2O has a molecular mass of 203.30 gmol what is the numeric value of x in the formula?
This formula is for magnesium chloride hexahydrate: MgCl2.6H2O.
A multiple of an empirical formula is often called what?
