Explanation:
Answer is: another name for groups of elements is family.
There are 18 numbered groups in the periodic table.
The elements in a group have similar physical or chemical characteristics and some groups have a specific name, for example group 17 (the halogens).
Elements in the group have the same number of valence electrons, for example, chemical elements in group 15 of the periodic table have neutral atom with a valence electron configuration of ns²np³.
In Chemistry, groups of elements are often referred to as families or groups.
In Chemistry, groups of elements are often referred to as families or groups. These groups are organized based on similar properties and characteristics. For example, the alkali metals (group 1) and the halogens (group 17) are two well-known families of elements.

The material with the density equivalent to the unknown piece has been Gypsum. Thus, the unknown piece has been gypsum.
Density can be defined as the mass of the substance per unit volume.
To calculate the density of the unknown piece, the mass has been calculated as:
Mass of unknown piece = Mass of weighing boat with the unknown piece - Mass of weighing boat
Mass of unknown piece = 18.01 g - 2.69 g
Mass of unknown piece = 15.32 grams.
The volume of the unknown piece can be calculated as:
The volume of unknown piece = Final volume - Initial volume
The volume of the unknown piece = 32.3 mL - 25.7 mL
The volume of the unknown piece = 6.6 mL.
The density can be expressed as:
Density =
The density of the unknown piece =
The density of the unknown piece = 2.32 g/mL.
From the given set of pieces, the material with the density equivalent to the unknown piece has been Gypsum. Thus, the unknown piece has been gypsum.

Answer : The identity of the substance is gypsum.
Explanation : Given,
Mass of weighing boat = 2.69 g
Mass of unknown pieces including weighing boat = 18.01 g
Initial volume = 25.7 mL
Final volume = 32.3 mL
First we have to calculate the mass of unknown pieces.
Mass of unknown pieces = Mass of unknown pieces including weighing boat - Mass of weighing boat
Mass of unknown pieces = 18.01 g - 2.69 g
Mass of unknown pieces = 15.32 g
Now we have to calculate the volume of unknown pieces.
Volume of unknown pieces = Final volume - Initial volume
Volume of unknown pieces = 32.3 mL - 25.7 mL
Volume of unknown pieces = 6.6 mL
Now we have to calculate the density of unknown pieces.
Now putting all the given values in this formula, we get:
From the given table we conclude that the unknown piece is gypsum whose density is 2.32 g/mL.
Therefore, the identity of the substance is gypsum.
