Question

Define following parts:-
a. Molecular mass b. Relative formula mass c. Isobars d. Cation e. Anion

Answer 1

Hey Ankit !

》Molecular Mass : The mass of a molecule that is equal to the sum of the masses of all the atoms contained in the molecule.

》Relative Formula Mass : The relative formula mass of a substance is the weighted average of the masses of the formula units relative to 1/12 of the mass of a carbon-12 atom.

》Isobars : Isobars are atoms of different chemical elements that have the same number of nucleons.

》Cation : A positively charged ion that would be attracted to the cathode in electrolysis.

》Anion : A negatively charged ion that would be attracted to the anode in electrolysis.

Hope it helps..!!

Answer 2

● Molecular mass= Molecular mass is the atomic mass of an atom in grams.
Ex... Molecular mass of water H2O= 18g

●Relative formula mass= It shows mass of an element compared with the mass of another element. Ex... Relative formula mass of sodium hydroxide NaOH is 40

● Isobars= Isobars are atoms having the same mass number but different atomic number. Ex.. Calcium atomic number is 20 and argon atomic number is 18 but both have mass number 40

●Cation= positively charged ion. Ex.. Potassium K+.

● Anion= Negatively charged ion. Ex.. Chloride Cl-
