The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / mole
To convert moles to atoms:
atoms Sc = 0.638 mol Sc6.02 x 1023 atoms Sc = 3.84E+23 atoms Sc
1 mol Sc
Multiply by atoms per mole. Moles cancel out.
To find the number of atoms in a sample of scandium, you need to first calculate the number of moles using the molar mass of scandium (44.96 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. 341g of scandium is approximately 7.58 moles, which corresponds to 4.57 x 10^24 atoms.
That depends on how much of the substance you have. Assuming you mean in one formula, the answer is 7.
Scandium has the chemical symbol Sc and 21 is it's atomic number. A link is provided to the Wikipedia article on this (usually considered) rare earth element.
Mass Number - Atomic Number = Number Of NeutronsSo for Sc:45 -21 = 24 neutronsHowever there is also an unstable Sc isotope (0.6 s half-life time) with mass number 41, so this one has 20 neutrons.
Yes, SC (Scandium) is considered a transition metal.

Sc is a s block element. There are 1.16 molesin 52.3 grams.
I lived there 48 years about 100 miles inland from Myrtle Beach. Never saw a gopher or heard of any being in SC. But moles are out there indeed! In SC they like the northern part of the state and you'll finds tons of moles in N. Carolina.

The conversion factor you need for this problem is Avogadro's number.(6.02 x 1023 atoms scandium/1 mole scandium) = 1... OR ...(1 mole scandium/6.02 x 1023 atoms scandium) = 1Since you want to end up in units of moles of Sc, this goes in the numerator (on top). You want to convert from atoms Sc, so this goes in the denominator (on the bottom).atoms Sc1 mole Sc = moles Sc6.02E+23 atoms Sc
