Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
What is the formula unit of molecular compounds?
The molecular formula is the formula of a discrete (single) molecule of the substance.The formula unit is generally defined in the same way as the empirical formula, which is the simplest whole number ratio of the elementsChemical formula includes both molecular and formula units.Examples:-Benzene a molecule consisting of a ring of 6 carbon atoms each with a hydrogen attached:-molecular formula C6H6formula unit CH (which is the result you would get if you analysed the compound and worked out the atomic ratio of carbon to hydrogen.NaCl is ionic so you cannot write a molecular formula you express the compound simply as the formula unit (empirical formula)- in its simplest case NaCl (never Na2Cl2 or some such)How can you tell whether a formula is molecular formula or a formula unit. Well if the formula could be "simplified" like benzene C6H6 could be simplified to CH then you know its a molecular formula. Something like SO2 and TiO2, well you need to be told. (SO2 is molecular, TiO2 is ionic)
Would ionic or covalent molecules use the molecular formula or empirical formula?
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
What is the Molecular formula of sodas?
Soda is an ambiguous term that could mean any of several different things. It's been used to refer to sodium carbonate Na2CO3, sodium hydrogen carbonate NaHCO3, sodium hydroxide NaOH, and sodium oxide Na2O. It also is used to mean carbonated beverages, which are mixtures, not compounds, and therefore don't have molecular formulae.
Is c6h8positive a molecular ion?
C6H8+ ==== As formulated it could be nothing else but a charged molecule and an ion.
What is the molecular formula for antacids?
The molecular formula for a Antacide could be NaHCO3 or CaCO3.
What compound could have a molecular formula of C7H16?
This formula corresponds to several saturated isomers of heptane as 2-methylhexane, 3-methylhexane, 2,3-dimethyl pentane e.t.c.
Is c7h16 plus o2 equal to 7co2 plus 8h20?
How could it be? Where is the oxygen count? C7H16 + 11O2 -> 7CO2 + 8H2O
How do you calculate Molecular formula from empirical formulaWhat could you do with that information to determine that the empirical and molecular formulas are related to one another by a factor of 6?
In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.

What could be a molecular formula for the empirical formula C2H2?
Anything really. C4H4, C8H8, C100H100....

What is the common name for CHI?
Chicago.CHI is not valid as a molecular formula; such a compound could not possibly be stable.
What does a structural formula depict that a molecular formula does not?
Structural formulas show a representation of the molecular structure, while chemical formulas do not. This is especially important when multiple compounds have the same chemical formula, but a different molecular structure.
How are molecular and empirical formulas related?
An empirical formula may or may not be the same as a molecular formula. The empirical formula of a compound shows the smallest whole-number ratio of the atoms compound. The molecular formula tells the actual number of each kind of atom present in a molecule of the compound.
What does this formula represent c6h12o6?
This is the molecular formula of quite a few different sugars and also of some alcohols. If you wish more information you could consult wikipedia for this formula's page.
