Athermometer containing 8.3g of mercury has broken. if mercury ha a density of 13.6g/ml. what volume is spilled?

The volume of mercury spilled is 0.61 ml.

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of mercury= 8.3 grams

Density of mercury=

Putting in the values we get:

Thus the volume of mercury spilled is 0.61 ml.

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.
