Question

Identify the symbol used to represent Avogadro&#8217;s number.&#8203;a)MAb)AOc)ANd)NACorrect answer is option 'D'. Can you explain this answer?

Answer

Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022x10^23 mol-1 and is expressed as the symbol NA. Avogadro's number is a similar concept to that of a dozen or a gross.

Answer

Avogadro's number,N_A,is defined as the number of atoms in 12 gram of carbon-12 atoms in their ground state at rest.

By definition it is related to the atomic mass constant m_{u b}y the relation.

Avogadro's number are defined in terms of the atomic mass constant (one twelfth of the mass of a 12C atom).

Avogadro's constant and number have by definition the same numerical value. In practice the two terms are used interchangeably.

Answer

We use this symbol because N here sybolises the number and subscript A shows the first letter of avagadro who discovered this

Answer

Option d is the right answer

Answer

Understanding Avogadro's Number
Avogadro's number is a fundamental constant in chemistry that relates the number of particles, such as atoms or molecules, in one mole of a substance. The value of Avogadro's number is approximately 6.022 x 10^23.
Symbol for Avogadro's Number
The symbol commonly used to represent Avogadro's number is 'NA'. This symbol is derived from the name of the Italian scientist Amedeo Avogadro, who contributed to the understanding of gas laws and molecular theory.
Options Analysis
- a) MA: This option does not relate to Avogadro's contributions.
- b) AO: This is not a recognized symbol for Avogadro's number.
- c) AN: This option could be misleading as it does not directly reference Avogadro.
- d) NA: Correct! This is the accepted symbol for Avogadro's number.
Importance of Avogadro's Number
- Mole Concept: Avogadro's number is essential in the mole concept, linking the macroscopic world (grams) with the microscopic world (atoms and molecules).
- Stoichiometry: It plays a crucial role in stoichiometric calculations in chemical reactions, allowing chemists to predict the amounts of reactants and products involved.
Conclusion
In summary, the correct symbol for Avogadro's number is 'NA' (option D). Understanding this concept is vital for students studying chemistry, as it lays the foundation for further exploration of chemical equations and molar calculations.
