Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Definition of Atomic Mass Unit (amu)**: - The atomic mass unit (amu) is a standard unit of mass that is used to express the masses of atoms and molecules. 2. **Purpose of AMU**: - AMU is primarily used to compare the relative masses of different isotopes of elements. Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons. ...

    In chemistry, 'mole' is an essential tool for the chemical calculations. It is a basic SI unit adopted by the 14th general conference on weights and measurements in 1971. A mole contains as many elementary particles as the number of atoms present in 12g of .^(12)C . 1 mole of a gas at STP occupies 22.4 litre volume. molar volume of solids and liquids is not definite Molar mass of a substance is also called gram-atomic mass or gram molar mass. the virtual meaning of mole is plenty. heap of the collection of large numbers. 1 mole of a substance contains 6.023xx10^(23) elementary particles like atom or molecule. Atomic mass unit (amu) is the unit of atomic mass, e.g., atomic mass of single carbon is 12 amu. The mass of one amu is approximately.
