What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
C4H6. C2H3 gives a molecular mass of 27, 54/27 gives 2. Therefore the molecular formula is twice the empirical formula.
What information is given by a molecular formula?
the empirical formula and the molar mass
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.
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 do you know about chemical compound by looking at it's chemical formula?
the number and kinds of atoms in the compoundIn an ionic compound, the formula gives the ions and their ratios in the crystal lattice. In a molecular compound, the formula gives the numbers of atoms of each element in a molecule.
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.
What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
C4H6. C2H3 gives a molecular mass of 27, 54/27 gives 2. Therefore the molecular formula is twice the empirical formula.
Which modeling method only gives information about the number and identity of atoms in a molecule?
Molecular Formula
What is the difference between a structural formula and a molecular model?
A chemical formula is the number of atoms in a substance, and is the same as a molecular formula (provided the substance is a molecule - if not, it has no molecular formula). A structural formula shows how the atoms are linked, and there are different interpretations of this: eg C3H8O2 is the chemical formula of 1,2 propan di-ol, which is the same as the chemical formula of 1,1 propan di-ol the structural formula however is CH2OHCHOHCH3 for 1,2 propan di-ol and CH(OH)2CH2CH3 for 1,1 propan di-ol. A displayed formula shows all the bonds: ........H..OH...H.............O-H...H...H ........|....|.....|..................|....|.....| ....H-C.-.C.-.C.-.H.....H-O-C.-.C.-.C.-.H ........|....|.....|..................|....|.....| ....H-O...H....H.................H...H....H 1,2 propan di-ol........1,1 propan di-ol ---------------------------------- Some chemicals, such as table salt, have no molecule. Thus, they only have chemical formula but not molecular formula. The chemical formula of table salt is NaCl. There are other salts, such as Na2SO4, MgSO4, etc. (If you hear people saying "the salt molecule has the formula of NaCl...", believe me, they do not know what they are talking about.) Some compounds exist as molecules- discrete entities, such as water. This kind of compounds have molecular formula. Water's is H2O. Structural formula? Never heard of.
What information is given by a structural formula that is not given by a simple formula?
A structural formulae gives many informations, out of which some are, number of bonds between two molecule, angle of bonding, etc. Which can be never expressed in a simple formulae.
What is the difference between a molecular and a structural formula?
A chemical formula that shows how atoms are arranged within a molecule or polyatomic ion and a molecular formula shows the number of the atoms that makes up the molecule.A molecular formula indicates the numbers and types of elements in one molecule of a substance. A structural formula indicates how the atoms are bonded to one another. Some examples include:water: H2O, H-O-Hcarbon dioxide: CO2, O=C=Ooxygen: O2, O=OIn a structural formula, each line represents a single covalent bond (one pair of shared electrons) between the atoms, and a double line represents a double covalent bond (two pairs of shared electrons) between the atoms.
How are the empirical and molecular formulas for a compound. Related?
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.
Why do geometrical isomers differ in their physical and chemical properties?
Isomers differ in their structural formulas. For example, the chemical formula for the simple sugars glucose, fructose, and galactose is C6H12O6, but their structural formulas are different, which gives them different properties. Glucose, fructose, and galactose are isomers of one another.
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)
What is the chemical formula for toluene?
One version would be CH3C6H5.
What is molucler formula?
A molecular formula is what determines the definite amount of atoms in a chemical compound. It gives the number and type of atoms in the compound.
What information is given by a molecular formula?
the empirical formula and the molar mass
