please tell me a quick for determination of empirical and molecular formula and also who invented it.
The empirical formula represents the simplest whole number ratio of elements present in a compound, while the molecular formula represents the actual number of each element present in a molecule.
To calculate the empirical formula, you need to determine the mass of each element present in the compound and convert it into moles. Then, divide each element's moles by the smallest number of moles to get the simplest whole number ratio.
The empirical formula is important because it provides a simple way to represent the composition of a compound and allows for easy comparison of different compounds.
The molecular formula is either the same as or a multiple of the empirical formula. The multiple is determined by dividing the compound's molecular mass by the empirical formula's molar mass.
Yes, in some cases, a compound's empirical and molecular formula may be the same. This occurs when the compound's molecular formula is already the simplest whole number ratio, so it cannot be reduced any further.
