Total density of filled ball with hydrogen gas:
The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d). The ball filled with hydrogen will float in the air because total density of filled ball is lessor than the density of an air.
Density of hydrogen gas =

Answer:
Organisms need to take food to get energy and perform life processes. A living organism undergoes many life processes like nutrition, respiration, digestion, transportation, excretion, circulation of blood, and reproduction. To perform all these life processes the organism needs energy and nutrients.
Explanation:
nnastarannnn his idea
If atomic number is 26 than electronic configuration would be 1s2s2p3s3p3d
there are two electrons in 1s
two electrons in 2s
six electrons in 2p
two electrons in 3s
six electrons in 3p
eight electrons in 3d
valence electron is 3 so 3s3p3d = 2+6+8
=16 electrons in valence shell
