The unknown mineral is gold because of the similar properties of gold to that unknown mineral.
<h3>What is unknown mineral?</h3>
The unknown mineral is Gold because it has similar properties to the gold. Gold has density of 19.3 grams per cubic centimeter which is same to this unknown mineral. The hardness and mass of the mineral are also similar to the Gold.
So we can conclude that the unknown mineral is gold because of the similar properties of gold to that unknown mineral.

Hey,
<h3><u>
QUESTION)</u></h3>
The mass of 6,022 × 10²³ molecules of a substance is called its molar mass.
- In fact this number represents the Avogadro Constant characteristic of the number of entities contained in a mole.
The molecular shapes which have the most electron pairs (both shared and unshared) around the central atom are linear-shaped.
<h3>What are molecular shapes?</h3>
The molecular shapes are the shapes like linear, trigon planner, octahedral, tetrahedral, etc. which depend on the number of atoms and the lone pair and bond pair of atoms.
In linear shape, a maximum number of electrons take part in the hybridization and can also have lone pairs to give repulsion to the bond pairs of the atoms and only 2 electrons take part in bond formation.
Therefore, linear-shaped are the molecular shapes that have the most electron pairs (both shared and unshared) around the central atom.
