Question

How to calculate molecular formulas? ​

Answer 1

Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.

Answer 2

Hey mate✌✌

Here is your answer

1. Determine the molecular formula of the molecule.
2. Determine the molecular formula of the molecule.Use the periodic table to determine the atomic mass of each element in the molecule.
3. Determine the molecular formula of the molecule.Use the periodic table to determine the atomic mass of each element in the molecule.Multiply each element's atomic mass by the number of atoms of that element in the molecule. This number is represented by the subscript next to the element symbol in the molecular formula.
4. Determine the molecular formula of the molecule.Use the periodic table to determine the atomic mass of each element in the molecule.Multiply each element's atomic mass by the number of atoms of that element in the molecule. This number is represented by the subscript next to the element symbol in the molecular formula.Add these values together for each different atom in the molecule....
