The meaning of MOLECULAR FORMULA is a chemical formula that gives the total number of atoms of each element in each molecule of a substance. How to use molecular formula in a sentence.
Molecular formulas give the kind and number of atoms of each element present in a molecular compound. In many cases, the molecular formula is the same as the empirical formula. The molecular formula of methane is \(\ce{CH_4}\) and because it contains only one carbon atom, that is also its empirical formula.
Molecular Formula Definition: An expression which states the number and type of atoms present in a molecule of a substance. Examples: There are 6 C atoms and 14 H atoms in a hexane molecule, which has a molecular formula of C 6 H 14 .
The molecular formula gives the number and type of atoms in the molecule. Sometimes the empirical formula and molecular formula are the same. For example, H 2 O is both the empirical and molecular formula of water.
A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. An empirical formula gives the simplest, whole-number ratio of atoms in a compound.
Molecular Formula. A molecular formula is a chemical formula of a molecular compound that represents the numbers of atoms of each element present in a molecule of the compound. Ammonia is a compound of nitrogen and hydrogen as shown below: Figure \(\PageIndex{2}\): The molecular formula for ammonia.
A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. An empirical formula gives the simplest, whole-number ratio of atoms in a compound.
A chemical formula that shows the total number and kinds of atoms in a molecule, but not their structural arrangement. For example, the molecular formula of aspirin is C . 9 H 8 O 4 .
The molecular formula shows the exact number and type of atoms present in a single molecule of a compound.
A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. (A subscript is used only when more than one atom of a given type is present.)
