Moreover, elements with heavier atomic mass were naturally more decoupled and unpredictable in space than those with lighter mass. Only the coupling of carbon, nitrogen and phosphorus, which are essential to life on Earth, deviated from this predictable pattern, suggesting that this anomaly may be...

Text SolutionVerified by Experts As atomic mass of M is a, 16x of O is attached with 2a of M, ∴ 8x of O is attached with (2a/16x)×8 of M=a/x of M hence. Equivaelent weight of M is an. Show More | ShareSave Class 11CHEMISTRYSOME BASIC CONCEPTS OF CHEMISTRY ...
To find the atomic mass of an element given the weight of one atom, we can use the relationship between the mass of a single atom and the number of atoms in one mole (Avogadro's number). Here’s how to solve the problem step by step:1.
