THIS IS YOUR ANSWER

The statement for the number of molecules are contained in hydrogen gas "3.01 x [tex]10^{23}[/tex] molecules."

What is a molecule?

Chemical bonds hold two or more atoms together in a molecule. If they have more than single atom, the atoms can be the same (for example, an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom).

1 mole of H2 will be of 6.022 x [tex]10^{23}[/tex] molecules H2

Then,

= 0.500 mol × 6.022 x [tex]10^{23}[/tex] molecules

= 3.01 x [tex]10^{23}[/tex] molecules of H2

As a result, 0.500 mol of H2 contains 3.01 x [tex]10^{23}[/tex] molecules

Hence, the correct option is D.
