Answer 1

Answer:

sure yrr.. class bnd Krna Bura hai.. BTW here u go..

Explanation:

The mole concept is method of expressing the amount of substance.

Mole:-

The number 6.02214076*1023 is popularly known as the Avogadro constant and is often denoted by the symbol ‘NA’. The elementary entities that can be represented in moles can be atoms, molecules, monoatomic/polyatomic ions, and other particles (such as electrons).

For example, one mole of a pure carbon-12 sample will have a mass of exactly 12 grams and will contain 6.022*1023 number of 12C atoms. The number of moles of a substance in a given pure sample can be represented by the following formula

Hope u understood!!!

Answer 2

Mole concept:

1 mole of a substance is equal to its atomic mass or molecular mass expressed in grams.

The atomic mass expressed in grams is the gram atomic mass.

The molecular mass expressed in grams is the gram molecular mass.

For example

The atomic mass of sodium is 23 grams.

Therefore, 23 grams of sodium is equal to one mole of sodium atoms.

Similarly, the molecular mass of oxygen (O2) =  2 × Atomic mass of oxygen

                                                          = 2 × 16 = 32 g

So, 32 grams of oxygen is equal to one mole of oxygen molecules.

1 mole (of anything) = 6.022 × 1023 in number
