The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

Answer : The mass of the helium in the blimp is, 1.1216 Kg

Solution : Given,

Volume of helium in the blimp =

conversion :

Density of helium in the blimp =

Formula used :

Now put all the given values in this formula, we get the mass of helium in the blimp.

Therefore, the mass of the helium in the blimp is, 1.1216 Kg

hi,

the answer is d, it has indefinite shape but definite volume.

hope this !

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
