Element Element's atomic mass
C : 12
H2 : 2(hydrogen's Atomic Mass is 1 but remember there are two)
O : 16
Add all the elements atomic mass and then divide the molecular mass by it. After that you only need to multiply all the subscripts of each element to find your answer.
12+2+16=30
240/30=8
8(CH2O) = C8H16O8

∙ 12y agoFind the molar mass of CH2O, which is roughly 30amus
Then divide the molecular mass of 180.15amus by 30 = 6
Multiply each element by 6 to give C6H12O6

The actual molar ratio of elements in a compound as expressed by the subscripts in a formula is expressed in what?
molecular formula
What is a molecular formula?
The molecular formula specifies the actual number of atoms of each element in a molecule.
What specifies the actual number of atoms of each element in one molecule of a compound?
This is specified by the subscripted number directly next right-down to the atom's symbol.Example: Sulfuric acid: H2SO4 has 2 atoms of Hydrogen, 1 atom of Sulfur and 4 atoms of Oxygen per molecule H2SO4
What is the molecular formula for sodium hydroxide?
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
How can you find the molecular formula of a compound when its percentage composition is given?
Yes, if you have some additional information, such as the molecular weight. For instance, the molecules C2H4 and C4H8 have exactly the same percent composition, but they are very different molecules. So you need some other information to tell them apart than the percent composition.Answer ExpandedThis is kind of a trick question. By knowing the percent composition, you would easily be able to determine its empirical formula, but molecular formula is a bit different. The molecular formula is the actual number of atoms in a molecule, so in order to find the specific molecular formula of a substance, you would also need to know how many grams there is of that substance.(This explains the difference between C2H4 and C4H8)
The actual molar ratio of elements in a compound as expressed by the subscripts in a formula is expressed in what?
molecular formula
What is an emperical formula?
An empirical formula represents the simplest whole-number ratio of atoms in a compound. It does not provide information about the actual number of atoms present in a molecule. To determine the empirical formula, one must divide the subscripts of the compound's molecular formula by the greatest common divisor to obtain the simplest ratio.
How is a molecular formula writted?
Molecular formula is the Actual ratio of atoms of each element in the compound Ex. H20
What is the properly written empirical formula of a compound of molecular formula C6H12 with a molar mass equal to 84.16 gram per mol?
The information about the actual molar mass is superfluous. Given any molecular formula, the corresponding empirical may be obtained by dividing all the subscripts in the molecular by the largest integer that yield an integer quotient for each subscript. In the given formula, the empirical formula is CH2.
What is a molecular formula?
The molecular formula specifies the actual number of atoms of each element in a molecule.
Why is na2so4 not a molecular formula?
Because Na2SO4 is an ionic compound and so does not have actual molecules.
What specifies the actual number of atoms of each element inone molecule of a compound?
molecular formula
What is the simplest part of a compound?
The simplest form for a compound, called the empirical formula, gives the simplest whole-number ratio of the elements in the compound, and may differ from the actual molecular formula. For example, the molecular formula for glucose is C6H12O6. The empirical formula would be CH2O, which can be found by dividing the molecular subscripts by 6.
What formula represents the actual number of atoms of each element in a compound?
A formula that gives the ratio of elements in a compound is called an empirical formula. On the other hand, the formula that shows the number of atoms in each element present in a molecule is called a molecular formula.
What is the difference between empirical and molecular formula?
An empirical formula is one that shows the lowest whole number ratio of the elements present. The molecular formula shows the composition of the molecules. An example is phosphorus pentoxide, P2O5 empirical formula, P4O10 molecular formula.
What is the relationship between the empirical formula and the molecular formula?
An empirical formula contains the constituent elements in the lowest possible mathematical whole-number ratio. In some cases, this is the legitimate formula for the compound, particularly if the substance you're dealing with is an ionic compound. Sometimes, however, the actual formula, known as the molecular formula, is a whole-number multiple of the empirical formula. The molecular formula for glucose is C6H12O6. However, an empirically-derived formula for glucose would be CH2O, which is the lowest possible ratio of carbon, hydrogen, and oxygen in that compound.
What is the empirical formula for C5H15O5?
The requirements for an empirical formula are that it give the correct ratios between all pairs of atoms in the actual molecule and have subscripts (including the value 1 implied by lack of an explicit subscript) with the lowest possible values to achieve all the correct ratios. To meet the latter condition, either one subscript must be one or the two smallest subscripts must be distinct prime number. The formula of the compound given has only one prime number subscript, 5. If all subscripts in the molecular formula are divided by the same number to yield an integral quotient, the resulting formula will still be empirically correct. In the given molecular formula, all the subscripts are integrally divisible by 5. Therefore, the empirical formula is CH3O2.
