Step 3: The relationship between Avogadro's number
, atomic mass unit and mass was explained in the following way: It was determined experimentally that there are as many [sup.12]C atoms as Avogadro's number
in 12.00000 gram [sup.12]C, and the mass of one [sup.12]C atom was accepted as 12 amu according to the definition of amu.
sup.3]/mol) [N.sub.A] Avogadro's number
([equivalent to] 6.023 x [10.
From Avogadro's number
, you could calculate the actual mass of a hydrogen molecule, since it would be 2 grams divided by six hundred billion trillion.
These students are not replicating Avogadro's Number
experiment; rather, they are engaged in a legitimate inquiry that will produce information that is not available and that is relevant to their own lives.
where h is Planck's constant, N is Avogadro's number
and the other symbols have their usual meanings.
The molecular mass of P2VP brushes ([M.sub.n,P2VP]) is given by [M.sub.n,P2VP] = [DELTA][Vd.sub.P2VP][N.sub.A], where [DELTA]V (5.766 X [10.sup.-16] [cm.sup.3]), [d.sub.P2VP] (1.20 g/[cm.sup.3]) , and [N.sub.A] (6.025 X [10.sup.23] [mol.sup.-1]) are the volume of the P2VP brushes, the P2VP density, and Avogadro's number
And, of course, homeopathy's modus of action based on a highly diluted substance exceeding Avogadro's number
was lambasted as absolute pseudoscience; one physicist was quoted as saying that a remedy of 30C potency would require an inconceivable volume to contain a single molecule of the original substance:
In this way, having an accepted value for the electron's charge, Millikan was also able to calculate the mass of the electron as well as other fundamental constants that previously relied on it, such as Avogadro's number
. More information can be found in Millikan's original publication (Millikan 1911).
h the Planck's constant, k the Boltzmann's constant, [N.sub.A] the Avogadro's number
, and Z the number of atoms given by
We determined the concentration of particles in each lipoprotein fraction mathematically using Avogadro's number
, the volume of sample measured, and the sample collection time.
