numericals on mole concept of gases

1 mole of an atom = 1 gram atomic weight of an ato..

Important relationships - 1 mole of an atom = 1 gram atomic weight of an atom 1 mole of a molecule = 1 gram molecular weight of molecule 1 mole of a gas = 22.4 liters of gas at STP 1 mole of a substance = 6.023 x 10 2 3 , atoms, molecules or ions Molecular we..

Since it is not possible to calculate the weight of particles individually, a collection of such particles called mole is taken for all practical purposes. It was discovered that the number of atoms present in 12g of carbon of 12 C isotope is 6.023 x 10 23 atoms. This is referred to as Av..

Introduction - In the year 1801, Robert Boyle and Charles had deduced the gas laws and proved them. They had confirmed that equal volumes of all the gases behave similarly, under similar conditions of temperature and pressure and the volumes of reacting gases and their gaseous p..

Mole Concept - In chemistry the term mole represents a pile or mass of atoms, molecules, ions or electrons. Just as common man measures quantity in terms of kilograms or dozens, a chemical scientist deals with a 'mole' of atoms, molecules, ions or electrons. ..
