JEE Main Chemistry Important Formulas 2024 - Download PDF

JEE Main Chemistry important formulas must be kept handy for ready reference for quick revision purposes. Keeping a formula book or a PDF saves a lot of time as it does not require referring to the textbook everytime a formula is forgotten or needs to be referred to.

The most important topics in Chemistry for which the formulas must be remembered are Stoichiometry, Gaseous State, Chemical Equilibrium, and Ionic Equilibrium among others.

JEE Main is an entrance examination that is conducted on an all-India basis to admit students to various engineering colleges where the JEE Main scores are accepted.

3. Mass number = No. of protons + No. of neutrons ; C= vλ

4. T(K)= T(0C) + 273.15

5. Molarity (M)= No. of Moles of Solutes/ Volume of Solution in Liters

6. Molecular Mass = 2 x vapor density

7. Charles’s Law: V1/ T1 = V2/ T2 (at constant P and n)

8. Boyle’s Law: P1V1 = P2V2 (at constant T and n)
