A formula unit.
What else can I help you with?
Which substance shows a substance that is not molecular?
A formula unit.
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
Can one substance have same empirical and molecular formula?
Yes, it is possible for a substance to have the same empirical and molecular formula. This can occur when the substance is composed of only one type of element, such as oxygen gas (O2), where both the empirical and molecular formula are O2.
What is the molecular formula of silver?
Ag is the molecular formula for silver. If you look on a periodic table, you will find this substance with the transitional metals and with the atomic number of 47.
What is identity of a substance?
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
What is the molecular formula of a substance that has an empirical formula of C2H5 and a molecular mass of 58 grams per mole?
The empirical formula of C2H5 corresponds to an empirical mass of 29 g/mol. To find the molecular formula from the empirical formula and molecular mass, divide the molecular mass by the empirical mass to get the "scaling factor" (58 g/mol ÷ 29 g/mol = 2). Multiply the subscripts in the empirical formula by the scaling factor to get the molecular formula: C2H5 x 2 = C4H10. So, the molecular formula is C4H10.
What does a compound formula tell you?
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
What is the that shows the no. of atoms and it's kind in a substance?
The molecular formula provides these information .
Can molecular formula be used to show difference between isomers?
No, molecular formula alone cannot show the difference between isomers. Isomers have the same molecular formula but different structural arrangements of atoms. Additional information, such as structural formula or connectivity of atoms, is needed to differentiate between isomers.
Do A molecular formula show the arrangement of the atoms in a molecule?
Yes.
What is carbon dioxides chemical substance?
Carbon dioxide is a molecular compound with the formula CO2
What other information is required to know whether a formula is both empirical and molecular?
We need to know the elements contained in this molecule and the percentages.
