How many atoms are present in 4 molecules of naoh?

The approximate molar mass of NaOH is 40 g/mol. You have 4 g NaOH.

No. of moles of NaOH is given by

n=(Given mass)/(Molar mass)

= 4/40 = 0.1 mol

1 mol has 6.022 × 10^23 molecules.

Thus, 0.1 mol has 6.022 × 10^23 × 0.1 molecules i.e. 6.022 × 10^22 molecules.

Explanation:

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

and ur welcm

: )

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
