Give some examples for mole concept ( no. Of moles =given mass / molar...
Examples of Mole Concept:
- Example 1: Finding the number of moles in a given mass of substance
Given Mass: 24 grams
Molar Mass: 12 g/mol
Number of moles = 24 g / 12 g/mol = 2 moles
- Example 2: Calculating the mass of a substance given the number of moles
Number of Moles: 0.5 moles
Molar Mass: 16 g/mol
Mass = 0.5 moles x 16 g/mol = 8 grams
- Example 3: Determining the number of atoms or molecules in a given mass of substance
Given Mass: 48 grams
Molar Mass: 32 g/mol
Number of moles = 48 g / 32 g/mol = 1.5 moles
Number of molecules = 1.5 moles x 6.022 x 10^23 molecules/mol
- Example 4: Finding the mass of a compound given the number of molecules
Number of Molecules: 3 x 10^23 molecules
Molar Mass: 18 g/mol
Number of moles = 3 x 10^23 molecules / 6.022 x 10^23 molecules/mol = 0.5 moles
Mass = 0.5 moles x 18 g/mol = 9 grams
The mole concept is a fundamental part of chemistry that allows us to relate the mass of a substance to the number of particles it contains. By using the formula "number of moles = given mass / molar mass," we can easily calculate the number of moles in a given mass of substance or vice versa. This concept is essential in stoichiometry calculations and understanding the composition of chemical reactions.
