The molar mass of copper is approximately 63.5 g. To find how many of these are in our sample we must divide.0.0159/63.5 = 2.5 x 10 ^ -4 = 0.00025 moles.
Each mole contains the Avogadro number of atoms, i.e. 6.023 x 10 ^ 23, so in total we have
0.00025x 6.023 x 10 ^ 23 = 1.51 x 10 ^ 20 atoms approximately.

A sample of gold has a mass of 5.00 x 10-3g. what amount of gold in atoms does the sample contain?
5x10-3 g divided by m.wt. of gold (197 g/mol) equals 2.5x10-5 mol gold.2.5x10-5 mol gold multiplied by Avogadro's Number (6.023x10+23 atoms/mol) equals 1.5x10+20 atoms.
How many sulfur atoms are in 0.45 mol BaSO4?
0.45 mol BaSO4 have 2,698.10e23 sulfur 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.
How many atoms are present in a 15 mol sample of uranium?
Approx. 9.1024 atoms.
The mass of a sample of nickelaverage atomic mass 58.69 amu is 11.74g how many atoms does it contain?
the number of atoms is equal to the mass of the sample divided by its molar mass times one mole 11.74g / 58.69g/mol * 6.02*1023 atoms/mol = 1.2*1023 atoms approximately
How many atoms of phosphorus are in a 0.577 g sample?
1.12 x 10^22 atoms PFirst determine the number of moles in the 0.577 g sample of phosphorus, determine the number of moles in the sample. Then multiply the moles by 6.022x10^23 atoms/mol.0.577 g P x (1 mol P/30.974 g P) x (6.022x10^23 atoms P/1 mol P) = 1.12 x 10^22 atoms P
How many atoms of sodium na are in 7 mol of sodium answer in units of atoms?
the constant Mole (mol): 6.02 x 10^23 are how many atoms you have per mol so the answer can be 7 mol atoms or 6.02 x 10^23 atoms per mol x 7 actual answer is 4.214 X10^24 atoms in 7 mol
How many atoms are present in 1.5 mol of sulfuric acid?
A mol = 6,022x10^23 atoms 1,5 mol = 9,033x10^23 atoms Always.
The mass of argon is 6.63 x 10-24g How many atoms are there in a 40.0 g sample argon?
just divide the mass of sample by the mass of argon. OR: atomic mass of argon is 40 g/mol, so in a 40g sample of argon, there ought to be 1 mole atoms, or 6.02x10^23 atoms
How many iron atoms are present in 55.845grams of Iron?
Amount of Fe = 55.845/55.845 = 1mol There is 1 mol of Fe in a 55.845g sample. 1 mol of Fe contains 6.02 x 1023 atoms (avogadro constant). Therefore there are 6.02 x 1023 atoms in 55.845g of iron.
How many atoms are there in a 0.250 mol sample of vanadium?
0.250 X Avogadro's Number = 1.51 X 1023, to the justified number of significant digits.
A sample of gold has a mass of 5.00 x 10-3g. what amount of gold in atoms does the sample contain?
5x10-3 g divided by m.wt. of gold (197 g/mol) equals 2.5x10-5 mol gold.2.5x10-5 mol gold multiplied by Avogadro's Number (6.023x10+23 atoms/mol) equals 1.5x10+20 atoms.
What is the number of Cl- ions in 21.04 gram sample of AlCl3?
1 mol of AlCl3 has mass 133.5 g and has 3 mol Cl- atoms so 400.5 g AlCl3 means 3 mol AlCl3 which means 9 mol Cl- atoms. So Ans = 9 X 6.022 X 1023 = 5.4198 X 1024 Cl- atoms
How many atoms are in 0.200 mol of pb?
There are 1.204 x 1023 atoms in .200 mol of Pb.
