Avogadro's number, or constant, is the number to which the mass of an atom must be multiplied to give a mass in grams numerically equal to its relative atomic mass that sounds like a mouthful, but it just means that an avogadro number of carbon atoms has a mass of 12g, because the relative mass of carbon = 12.

Avogadro’s number is defined as the number of elementary particles (molecules, atoms, compounds, etc) per mole of a substance it is equal to 6022×10 23 mol-1 and is expressed as the symbol n a avogadro’s number is a similar concept to that of a dozen or a gross a dozen molecules is 12 molecules a gross of molecules is 144 molecules. Avogadro’s constant is the number of particles (atoms or molecules) in one mole of any substance for example, 12 grams of carbon contains 602214129 x 10 23 carbon atoms avogadro’s constant is an enormous number. The avogadro constant is a huge number (approximately 602 x 10 23) it has units of mol-1, which you would read as per mole in other words, there are 602 x 10 23 of whatever formula units you are talking about per mole of that formula.

I'm a bit confused about the terms mole, avogadro's number, avogadro's constant and the avogadro constant and the concept - or concepts.

- In chemistry and physics, the avogadro constant is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole.
- The terms, mole, avogadro’s number and avogadro’s constant are related to each other a mole is a unit used to measure the amount of a substance it can be used to measure any type of chemical substance the value of one mole is 6022 x 10 23 this is called the avogadro’s number.
- Enter avogadro’s number (avogadro’s constant), 602214179 × 1023—the number of units in one mole of a substance the moles of chemistry—far from cute and fuzzy and certainly not conveying the kind of hilarity found in the mole scene in austin powers in goldmember (2002)—are standard scientific units.
