A weather forecasting balloon of volume 12m contain hydrogen of density 0.09
kgm'. The mass of the empty balloon is 6.92 kg. The balloon floats in air of
density 1.3 kgm. The volume of the equipment carried by the balloon is
negligible compared to balloon's volume. Find the total mass of hydrogen and
balloon, the mass of air displaced by the balloon and mass of the equipment.
