Question

what is the formula for finding the atomicity

Answer 1

Answer:

There is a simple way to determine the atomicity of any element. It can be determined as a ratio of molecular mass and atomic mass. For example, using the case of oxygen molecule, the molecular mass is 32 (= 2x16), while the atomic mass is 16. If we divide the two, we get atomicity as 2 (=32/16).

Answer 2

Answer: no. Of atoms= give mass/molar mass× Na×no.of atom in one molecule

Explanation:

Ex: find the no. Of atoms in 18 g h2o?

Then what we have to do is put that formula

Like given mass 18 g

Molar mass 18 g

Na= 6.022×10²³

Atoms in one molecule= atom of h2 which is 2 and atom of o which is 8( as their atomic no.s)

Then put the values and solve it u will get ur ans.

Hope u get it and plz lemma know if it was good
