The <u>Mole</u> is the SI unit that expresses the amount of substance.
Mole is defined as - The mole is the amount of substance containing the same number of entities as there are in the 12 grams of Carbon - 12.
Mole is denoted by using symbol mol.
Mole = 6.022 x 10²³ elementary entities.
These number of elementary entities in 1 mole is equal to or called as an Avogadro's number. Mole is equal to 6.022 x 10²³ because this number of entity is same as in exactly 12 g of carbon-12.
It is a very important SI unit of measured which is used by the chemists. Moles are used in measuring in small or tiny things such as atoms, molecules and the other tiny particles.

Explanation:
Answer: The average rate of the reaction during this time interval is, 0.005 M/s
Explanation:
The given chemical reaction is:
The expression will be:
where,
= final concentration of 
= 0.025 M
= initial concentration of = 0.100 M
= final time = 15 minutes
= initial time = 0 minutes
Putting values in above equation, we get:
Hence, the average rate of the reaction during this time interval is, 0.005 M/s
