The mole concept is important in chemistry

WebThe mole concept is a convenient method of expressing the amount of a substance. Any measurement can be broken down into two parts – the numerical magnitude and the magnitude’s units. For example, when a ball’s mass is measured to be 2 kilograms, the magnitude is ‘2’ and the unit is ‘kilogram’. When dealing with particles at an ... WebIn simple words, a mole is the number of atoms in exactly 0.012 kg (12 grams) of C-12. It should be noted that although mole is defined in terms of carbon atoms but the unit is applicable to any substance just as 1 dozen means 12 (1 dozen pen or 1 dozen banana) or one gross means 144 of anything.
