Question

please tell me fast I will mark u as brainliest​

Answer 1

1 mole of H₂ = 6.022 × 10²³ atoms

As H₂ is made from 2 atoms of hydrogen, so number of atoms is = 2 × 6.022 × 10²³ atoms.

Answer 2

Answer: 1.2046 x 10^24 atoms

explanation:

1 mole= 6.023 x 10^23 atoms/particles

H2 has 2 moles

hence, it would be 2 x 6.023 x 10^23

=1.2046 x 10^24 atoms

hope this answer helps you!!!

pls mark as brainliest!!!
