The general formula for a noncyclic alkene is CnH2n, where "n" represents an integer; for a mono cyclic alkene, the general formula is CnH2n-2.
CH2 is the empirical formula for C4H8 because it is an alkene and the empirical fomula for ALL alkenes are C(n)H(2n) n being the number of molecules!!! (^-^)
C5H10 can be both an alkane and an alkene. As an alkane, it would be pentane (C5H12), and as an alkene, it would be 1-pentene (C5H10). The presence or absence of a double bond in the molecule determines if it is an alkane or an alkene.
CH will be the empirical formula and C12H12 will be the molecular formula
The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula.
Benzene is equal parts hydrogen and carbon, and has C6H6 as it molecular formula. It is actually a ring with the carbons in the middle and the hydrogen bonded one-to-one with the carbon atoms on the outside. Use the link below for more information and to see a "picture" that cannot be drawn here.

It is an empirical formula.
C5H10 can be both an alkane and an alkene. As an alkane, it would be pentane (C5H12), and as an alkene, it would be 1-pentene (C5H10). The presence or absence of a double bond in the molecule determines if it is an alkane or an alkene.
A formula unit is an empirical formula.
CH will be the empirical formula and C12H12 will be the molecular formula
It Has No Empirical Formula.
An empirical formula has no data about the structure of a compound.
It has a molecular formula of C10H8 so that would make an empirical formula of C5H4.
In this instance, the empirical formula is the same as the formula unit: NaNO3
The empirical formula for potassium manganate is KMnO4.
The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula.
