FAQs on PYQs: Mole Concept Video Lecture - Physical Chemistry
| 1. What is the mole concept in chemistry? |  |
Ans. The mole concept in chemistry is a fundamental concept that relates the mass of a substance to the number of particles (atoms, molecules, ions) it contains. It states that one mole of any substance contains Avogadro's number (6.022 × 10^23) of particles.
| 2. How is the mole concept used in chemical calculations? | |
Ans. The mole concept is used in chemical calculations to determine the amount of reactants and products involved in a chemical reaction. It allows us to convert between mass, moles, and number of particles using molar mass and Avogadro's number.
| 3. How do you calculate the number of moles in a given mass of a substance? | |
Ans. To calculate the number of moles in a given mass of a substance, you divide the mass of the substance by its molar mass. The molar mass is the mass of one mole of the substance and is expressed in grams per mole.
| 4. What is the relationship between volume and moles in gases? | |
Ans. The relationship between volume and moles in gases is given by Avogadro's law, which states that equal volumes of gases, at the same temperature and pressure, contain an equal number of moles. This means that the volume of a gas is directly proportional to the number of moles present.
| 5. How does the mole concept help in determining the empirical formula of a compound? | |
Ans. The mole concept helps in determining the empirical formula of a compound by comparing the number of moles of each element present in a given mass of the compound. By dividing the number of moles of each element by the smallest number of moles obtained, you can determine the ratio of the elements and hence the empirical formula.
