Answer 2

Answer:

1)  1 mole of He contains 6.023x10^23

So, 52 moles of He contains 52 x 6.023 x10^23atoms

2) Atomic mass of Helium is 4u

= 2protons + 2 Neutrons = 1 atom 

So, The number of atoms in 52u = 52/4 = 13 atoms.

3) 4g of He has 1 mole 

=) 1g of He has 1/4 mole 

So, 52g of He has 1/4 x 52 = 13 moles 

Since, 1 mole=6.022x10^23atoms 

So, 13 moles 13x6.023x10^23 atoms.

Hope it helps☺️
