Question

calculate the number of atoms in 52g of He​

Answer 1

Answer:

13* Avogadro's Number

Explanation:

We will calculate moles first :-

Moles = weight / molecular mass

moles = 52 / 4 = 13

Atoms in 1 mole = Avogadro's Number

Atoms in 13 mole = 13 * Avogadro's Number

                             = 13 * 6.022 * 10 ^23
