how is the molecular formula of compound related to its emphrical formula
Answers
Answer:
Molecular formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's molecular formula cannot be reduced any more, then the empirical formula is the same as the molecular formula....
Answer:
The empirical formula of a compound refers to the simplest ratio of elements that can be obtained from the chemical formula of the compound.
Let’s consider glucose (C6H12O6) as an example; the ratio of C to H to O is 6 : 12 : 6, which when simplified, would be 1 : 2 : 1. Hence, the empirical formula of glucose is CH2O, or methanal.
Molecular formula, on the other hand, is based off empirical formula. It’s usually calculated via the following method:
((molecular mass of compound) / (emp. mass of compound)) * emp. formula.
So, going back to our glucose example, if the empirical formula is CH2O, and the molecular mass of glucose is 6 times that of methanal, then we can multiply the number of each atom in methanal to get glucose.
