Question

can anyone mention some points about Mole Concept??​

Answer 1

Answer:

You will study about concentration terms in mole concept . Here are some common terms used in mole concept-

1. %w/w( percentage weight by weight)

% w/w = weight of solute×100/ weight of solution

2. % v/v ( percentage volume by volume)

%v/v = volume of solute ×100/ vol. of solution

3. % w/v ( percentage by volume)

% w/v = weight of solute ×100/ vol. of solution

4. number of moles = Given mass/ Molecular mass

5. mole fraction = number of moles of a component/ total number of moles of all the components in the solution

6. Molarity (M)= number of moles of solute/ volume of solution ( in litre)

- it is a temperature dependent quantity.

7. molality (m) = number of moles of solute/ weight of solvent ( in kg).

8. normality (N) = number of equivalents of solute/ volume of solution ( in litre).

Answer 2

Answer:

yes until the end of the material which will help keep the faith in mole concept
