FAQs on Solved Examples: Mole Concept Video Lecture - Chemistry Class 11 - NEET

1. What is the mole concept and why is it important in chemistry?

Ans. The mole concept is a fundamental principle in chemistry that defines a mole as the amount of substance containing the same number of entities (atoms, molecules, ions, etc.) as there are in 12 grams of carbon-12. It is important because it allows chemists to count particles by weighing them, facilitating the calculation of reactants and products in chemical reactions.

2. How do you calculate the number of moles from mass?

Ans. To calculate the number of moles from mass, you can use the formula: Number of moles = Mass (in grams) / Molar mass (in g/mol). The molar mass is the mass of one mole of a substance, which can be found on the periodic table.

3. What is Avogadro's number and how is it used in the mole concept?

Ans. Avogadro's number, approximately \(6.022 \times 10^{23}\), is the number of particles in one mole of a substance. It is used in the mole concept to convert between the number of moles and the number of entities (atoms, molecules, etc.) in a sample.

4. How do you convert between moles and volume for gases?

Ans. For gases at standard temperature and pressure (STP), one mole of any gas occupies 22.4 liters. To convert moles to volume, use the formula: Volume (in liters) = Number of moles x 22.4 L/mol. Conversely, to find moles from volume, use: Number of moles = Volume (in liters) / 22.4 L/mol.

5. Can you explain the relationship between moles, mass, and molar mass with an example?

Ans. Yes! The relationship can be expressed with the formula: Mass = Number of moles x Molar mass. For example, if you have 2 moles of water (H₂O), and the molar mass of water is 18 g/mol, the mass would be: Mass = 2 moles x 18 g/mol = 36 grams.
