1.	Why relative atomic mass is compared with 1 /12 of carbon?
Answer» Naturally occurring hydrogen has three isotopes (₁H¹ , ₁H² and ₁H³ ) and its relative atomic mass works out 1.008 rather than 1. Atomic mass of carbon is 12. Thus, 1/12 mass of carbon work out as 1. It is on account of the above reason 1/12 mass of carbon is used for comparing relative atomic masses of other elements.
