Question

12g naoh contains
How many molecules
How many atoms

Answer 1

Explanation:

120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.

Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).

Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)

Answer 2

Explanation:

Molecules - NaOH is an ionic solid and has no molecules.There are N formula units per gram formula weight.

Atoms - Na-1 O-1 H-1 = 3 atoms
