How many atoms of lithium are in 18.7 g?
The gram Atomic Mass of lithium is 6.941; this is the amount of lithium that contains Avogadro's Number of atoms. Therefore, in 18.7 g of lithium, there will be (18.7)/(6.941) times Avogadro's Number of atoms, or about 1.62 X 1024, to the justified number of significant digits.
Which sample contains the greatest number of atoms a sample of Al that contains 8.18E plus 23 atoms or a 5.16 mole sample of S?
Which sample contains the greatest number of atoms. A sample of Al that contains 8.18E+23 atoms or a 5.16 mole sample of S?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 S to atoms of S.The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert 5.16 moles of S to atoms of S:atoms S=5.16 mol S6.02 x 1023 atoms S= 3.11E+24 atoms S1 mol SMultiply by atoms per mole. Moles cancel out.The sample of Al contains 8.18E+23 atoms.Since 3.11E+24 is larger than 8.18E+23, the sample of S contains the greatest number of atoms.
How many moles of Li atoms are in 10.56grams of Li?
How many lithium atoms are in 10.56 g of lithium
Who has more atoms 50g of magnesium or 50g of lithium?

In a sample of pure copper all atoms have the same what?
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
How many atoms of lithium are in 18.7 g?
The gram Atomic Mass of lithium is 6.941; this is the amount of lithium that contains Avogadro's Number of atoms. Therefore, in 18.7 g of lithium, there will be (18.7)/(6.941) times Avogadro's Number of atoms, or about 1.62 X 1024, to the justified number of significant digits.
How many oxygen atoms are present in a formula unit of lithium phosphate?

How many atoms are present in a 15 mol sample of uranium?
Approx. 9.1024 atoms.
How many lithium atoms are present in 0.01456 of lithium?
I assume you mean; 0.01456 grams lithium (1 mole Li/6.941 grams)(6.022 X 10^23/1 mole Li) = 1.263 X 10^21 atoms of lithium
What is the averaged Number of atoms?
the atomic no.of lithium is 3
In lithium atoms would all atoms be identical in terms of electrons neutrons and protons?
No. They will all have the same number of protons and electrons, but the number of neutrons will vary. This results in isotopes of lithium.
What is a collection of atoms called?
A large collection of neutral atoms with the same atomic number is a sample of an element. Elements include include lithium, hydrogen, neon, and oxygen. Note that different isotopes of elements exist; these are atoms with the same atomic number but having a different number of neutrons.
How many atoms are in a 0.250 mole sample of magnesium?
The number of atoms is 1,50553521.10e23.
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.
