more simple problems based on mole concept

Example: 5 - How many moles of sodium hydroxide are present in 3200 g of it? (Na=23, O=16, H..

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..

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...

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..
