The number of molecules of gases in each of the 3 vessels is the same.
Number of moles
The first vessel contains 2g of [tex]H_2[/tex] gas:
Number of molecules in 2 g = 2/2 = 1 mole
The second vessel contains 32 g of [tex]O_2[/tex] gas:
Number of molecules = 32/32 = 1 mole
The third vessel contains 44 g of [tex]CO_2[/tex] gas:
Number of molecules = 44/44 = 1 mole
Thus, the 3 vessels contain the same number of moles of gases.
