Best Answer

In one mole of helium, there is 6.02 x 10*23 atoms.

In 1 mole of any substance, it contains 6.02 x 10*23 particles of that substance.

This number (6.02 x 10*23) is known as Avogadro's number or Avogadro's constant.

1 mole of He = 6.022 x atoms

6.022 x atoms of He = 1 mole

1 atom of He = mole

6.022 x atoms of He = mole

A mole is equal to 6.022x10^23 number of "things". Those things could be anything.

They could be atoms or frogs or molecules or eggs or helium atoms.

Which sample contains the greatest number of atoms a sample of Mn that contains 3.29E plus 24 atoms or a 5.18 mole sample of you?

Which sample contains the greatest number of atoms. A sample of Mn that contains 3.29E+24 atoms or a 5.18 mole sample of I?The sample of _____ contains the greatest number of atoms.Answer:In order to compare the two samples, it is necessary to express both quantities in the same units. Since the question was phrased in terms of atoms, it is convenient to convert moles of I to atoms of I.The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert 5.18 moles of I to atoms of I:atoms I= 5.18 mol I6.02 x 1023 atoms I = 3.12E+24 atoms I1 mol IMultiply by atoms per mole. Moles cancel out.The sample of Mn contains 3.29E+24 atoms.Since 3.12E+24 is smaller than 3.29E+24, the sample of Mn contains the greatest number of atoms.


Is a 16.00-g sample of oxygen atoms contains the same number of particles as a 4.003-g sample of He atoms?

Yes. 16.00g of oxygen is its molar mass, which is the mass of one mole of oxygen. 4.003g is the molar mass of helium, which is also the mass of one mole of helium. One mole of anything is 6.022 x 1023. One mole of oxygen atoms is 6.022 x 1023 atoms of oxygen and one mole of helium atoms is 6.022 x 1023 atoms of helium.
