Question

what do you mean by Avogadro constant or Avogadro numbers ? Give one advantage of Avogadro number over a dozen and a gross.
​

Answer 1

Answer:

Hey mate,

Your answer is as follows:

A dozen molecules is 12 molecules. A gross of molecules is 144 molecules. Avogadro's number is 6.022×1023 molecules. With Avogadro's number, scientists can discuss and compare very large numbers, which is useful because substances in everyday quantities contain very large numbers of atoms and molecules.

Besides being related to a number, a mole has one more advantage over a dozen or a gross. This advantage is that mass of 1 mole of a particular substance is also fixed. The mass of 1 mole of a substance is equal to its relative atomic or molecular mass in grams.
