1.	Assertion: Molecular formula shows the exact number of different types of atoms present in a molecule of a compound. Reason : Molecular formula can be obtained directly from empirical formula which represents the simplest whole number ratio of various atoms present in a compound.
Answer» If both ASSERTION and REASON are true and reason is the correct explanation of assertion If both assertion and reason are true but reason is not correct explanation of assertion. If assertion is true but reason is false. If both assertion and reason are false. Solution :Molecular FORMULA can be OBTAINED from empirical formula is molar mass is known. Molecular formula = n X Empirical formula where, `n=("Molar mass")/("Empirical formula mass")`
