Question

Calculate the number of atoms of Helium in
i) 52g of Helium.
ii) 52u of Helium​

Answer 1

Answer:

52 g of helium = 52 × no of atoms contained in helium

Answer 2

Answer:

52g of helium--

1g of any gas consists of 6.022 x 10²² atoms.

one atom of helium has 4u of mass-

52 g helium has = 52 x 6.022 x 10²² atoms.

52 u helium has = 13 atoms
