hey friend
here your answer is
hope it helps you .✌

Answer 2

★ Ello ★

here is your answer !!

mole = mass / molecular mass


mole = 4 / 18


2 / 9 mol


now , number of molecules


2 / 9 × 6.22 × 10 ²³


total number of atom is


2 atoms of Hydrogen


1 atom of oxygen


total = 2+1 = 3


hence , the number of atoms present is


4 / 9 × 6 .22 × 10 ²³ × 3


=> 4 / 3 × 6 .22 × 10 ²³ atoms



hope it helps you dear !!
