How is a molecular formula writted?
Molecular formula is the Actual ratio of atoms of each element in the compound Ex. H20
C2H2 is a chemical formula for acetylene. Which type of chemical formula is this A molecular formula An empirical formula A structural formula?
C2H2 is a molecular formula because it shows the actual number of atoms of each element present in a molecule of acetylene.
To determine the subscript of an element in a molecular formula the empirical mass must be multiplied by the actual mass?
The actual mass must be divided by the empirical mass. This was derived from the following equation: (subscript)(empirical formula) = (molecular formula) subscript = (molecular formula)/(empirical formula)
What is the molecular formula for chromium?
Chromium is a metal. It is located in the 4th period of the periodic table. It is the element with the chemical abbreviation Cr.
Can the empirical formula of a compound be triple its molecular formula?
No, the empirical formula represents the simplest whole-number ratio of atoms in a compound, while the molecular formula shows the actual number of each element present in a compound. Therefore, the empirical formula cannot be triple the molecular formula.
What is the molecular formula of an element having 16 electrons?
It's 32.065 (± 0.005), and the element is sulfur (S).
Is chlorine molecular ionic or metallic?
The element chlorine at standard temperature and pressure is molecular and has the formula Cl2.
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.
What additional information do you need to determine the molecular formula?
To determine the molecular formula, you need the molecular weight of the compound, the empirical formula, and any information about the compound's structure or the number of atoms of each element present. Additionally, knowing the types of elements involved can also help in calculating the molecular formula accurately. If the empirical formula is known, the ratio of the empirical formula's mass to the molecular weight will help in finding the actual molecular formula.
Molecular formula for sodium?
Sodium is a chemical element not a molecule; the symbol is Na.
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.
What is the molecular formula for argon?
Argon is an element, not a molecule, and as such does not have a molecular formula, but rather a symbol - "Ar".
