Molecular mass of `CH_(4)` is

Calculate the molecular mass of CH_(4) molecule in amu.

Molecular mass of KMnO _(4) is

Calculate the molecular masses of H_(2), O_(2), Cl_(2), CO_(2), CH_(4), C_(2)H_(6), C_(2)H_(4), NH_(3), CH_(3)OH .

STATEMENT-1: The equivalent mass of of KMnO_(4) in acidic medium is (M)/(5) where M=molecular mass of KMnO_(4) STATEMENT-2: Equivalent mass is equal to product of molecular mass and change in oxidation number.
