Which formula represents the simplest whole number ratio of various atoms present in a compound?

Q. 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.

Q. Assertion (A) : The empirical mass of ethene is half of its molecular mass.Reason (R) : The empirical formula represents the simplest whole number ratio of various atoms present in a compound

Q.

Statement 1:Empirical formula gives the simplest ratio of different atoms present in a compound.

Statement 2: Molecular formula can be the same as the empirical formula.

Q. Which of the following statements about molecular and empirical formulas is\ are false?
I. A given compound can have the same, molecular and empirical formula.
II. The molecular formula is a whole number multiple of the empirical formula.
III. $H_2{O}_2$ represents the empirical formula of hydrogen peroxide.

Q. Assertion :The simplest types of chemical formulas are called empirical formulae. Reason: Empirical formula uses letters and numbers indicating the numerical proportions of atoms of each type.
