Answer 2

Answer:

one mole of any gas at STP has a volume of 22.4 L so first determine the number of moles of gas you have

67.3/22.5= 3 moles of H2 .

one mole of any substance contains Avogadro's number of atoms

=6.022x 10 power 23 atoms.

so multiply number of moles x number of atoms / mole =1.8066 x 10 power 24 atoms of H2.
