Question

Why do we always consider the relative atomic mass in stoichiometry? Why we don't take the real masses of atoms? please answer​

Answer 1

Explanation:

Different atoms have different masses. Atoms have such a small mass it is more convenient to know their masses compared to each other

Because atoms are so small (and subatomic particles are even smaller!), we can't easily use everyday units such as grams or kilograms to quantify the masses of these particles.
