I don't know the exact formula but, i know the density of iso-octane: 0.69 g/ml
And one gallon is equal to 3,840 ml so.... all you need is the volume.
The empirical formula is C8H18; the structural formula I'm not going to attempt to draw here but you should be able to figure it out from the IUPAC name: 2,2,4-trimethylpentane.
Octane and iso-octane both have the molecular formula C8H18, so empirical formula is C4H9.
It is an empirical formula.
A formula unit is an empirical formula.
An empirical formula has no data about the structure of a compound.
C5H6O is the empirical formula for Cortisol.
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.
It is an empirical formula.
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
A formula unit is an empirical formula.
A formula unit is an empirical formula.
An empirical formula has no data about the structure of a compound.
The empirical formula of water is H2O.
CH will be the empirical formula and C12H12 will be the molecular formula
X3Y is the empirical formula
C10H22 is the empirical formula of decane.
C5H6O is the empirical formula for Cortisol.
In this case, the empirical formula and the molecular formula are the same and it is K3PO4.
the empirical formula for fluorine is F. the chemical formula is F2.
