the molecular mass of 1 mole methane gas is (12×1)+(1×4)
=16gm
so the molecular mass of 5 mole methane gas is (16×5)
=80gm(ans)
volume of 5 mole methane gas is (22.4×5)
=112litre
the mass of 5 molecule methane gas is (80×1.6605×10^-24)kg
=132.24×10^-24 kg
the molecular mass of NH3 is(14×1)+(1×3)
=17gm
then in 68gm NH3 has 4 mole molecule
the volume of 68gm NH3 is (22.4×4)
=89.6litre
=16gm
so the molecular mass of 5 mole methane gas is (16×5)
