Question

which among the following has more number of molecules :1g of hydrogen (H2)or 1 g of methane (ch4),

Answer 1

Answer:

1 gram of hydrogen has more number of molecules.

Explanation:

Molecules= moles * Nₐ

                = mass/molar mass * Nₐ

                = 1/2 * 6.022*10²³

                = 3.011*10²³ molecules of hydrogen

Moleules= moles * Nₐ

              =1/16 * 6.022810²³

              =3.763*10²² molecules of methane
