Avogadro constant - Wikipedi

The Avogadro constant (N A or L) is the proportionality factor that relates the number of constituent particles (usually molecules, atoms or ions) in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined as N A = 6.022 140 76 × 10 23 mol −1. It is named after the Italian scientist Amedeo Avogadro. Although this is called Avogadro's. Avogadro's number, or Avogadro's constant, is the number of particles found in one mole of a substance. It is the number of atoms in exactly 12 grams of carbon -12. This experimentally determined value is approximately 6.0221 x 10 23 particles per mole Avogadro's Number. Avogadro's number tells us the number of particles in 1 mole (or mol) of a substance. These particles could be electrons or molecules or atoms. The value of Avogadro's number is approximately 6.022140857×1023 mol−1 The number \(6.02 \times 10^{23}\) is called Avogadro's number, the number of representative particles in a mole. It is an experimentally determined number. A representative particle is the smallest unit in which a substance naturally exists. For the majority of elements, the representative particle is the atom Since Avogadro's number is 6.022 × 10 23, it only makes sense that the holiday starts at 6:02 a.m. every Oct. 23. Revelers tell chemistry jokes, blow bubbles of natural gas that they set ablaze, toast with drinks chilled by dry ice and even recite the mole pledge of allegiance

The atomic mass constant m u has the mass 1. Avogadro's number. Avogadro's number is the number of molecules of gas in a mole. This number is huge, the current figure being 6.022 x 10 23. The unit for Avogadro's number is mol-1. This means that the measure of the entity in question is per mole. Avogadro's number is usually symbolised by N Avogadro's number, 6.022 * 10 23 is the number of things in one mole. The question indicates that there is 1 mole of H 2. Thus there are 6.022 * 10 23 molecules of H 2. However the question is asking for the amount of atoms in 1 mole of H 2
