Answer:

[tex]0.075\:moles[/tex]

Explanation:

Since, 1 molecule of hydrogen gas, there're 2 atoms of hydrogen:

1 mole of [tex]H_2[/tex]  has [tex]2\times 6.023 \times 10^{23}[/tex] atoms.

Switch sides and make it a equation.

1 atom of [tex]H_2[/tex]   =   [tex]\frac{1}{2\times 6.022\times10^{23}}[/tex] moles of [tex]H_2[/tex]

[tex]9.04\times 10^{22}[/tex] atoms of [tex]H_2[/tex]   =   [tex]\frac{9.04\times 10^{22}}{2\times 6.022\times 10^{23}}[/tex]  moles of [tex]H_2[/tex]
