To find the number of atoms in 0.25 moles of hydrogen, multiply 0.25 by . So, contains 2 hydrogen atoms.

Answer 2

Answer:

1. One mole of Hydrogen has 6.022 X 10^23 atoms.

2. Thus, 0.25 moles of H2 = 6.022 X 10^23 X 0.25

3. This gives us 6.022 / 4 X 10^23

4. The final answer is 1.5055 X 10^23 atoms of Hydrogen in o.25 moles of it.
