if you mean 10^22 O atoms, then this is how you do it:
(8.16X10^22)/2=4.08X10^22
so there are 4.08X10^22 molecules, divided by 6.022X10^23(1 mole) is
.06775, so there are that many moles of CO2. If you wanted to know how many moles of overall atoms there were, there's 4.08X10^22 molecules, 1 C in each so 4.08X10^22 C, and 8.16X10^22 O=1.224X10^23, and that's how many atoms, so that divided by 1 mole is (most accurate answer i can get you) .2032547326 moles of atoms
so
.2032547326 moles of atoms
or
.06775 moles of molecules/CO2
First, calculate the number of moles in the sample by dividing the number of O atoms by Avogadro's number (6.022 x 10^23). Then, since each CO2 molecule contains 1 C atom and 2 O atoms, you can determine the number of moles of CO2 by dividing the number of moles of O atoms by 2.
1.9 moles are in the sample of CO2. 1 mole of CO2 contains 1 mole of C and 2 moles of O.

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 moles of Cr are there in a sample of Cr that contains 4.37E 23 atoms?
To find the number of moles of Cr in the sample, first calculate the molar mass of Cr (chromium). Chromium has an atomic mass of approximately 51.996 g/mol. Next, divide the number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol) to convert atoms to moles. So, 4.37 x 10^23 atoms of Cr is equivalent to 0.725 moles of chromium.
How many moles of phosphorus atoms are there in 8 moles of P4O10?
There are 8 moles of P4O10, and each mole of P4O10 contains 4 moles of phosphorus atoms. Therefore, there are 32 moles of phosphorus atoms in 8 moles of P4O10.
How many moles of H are in 4.56 moles of NH2NH2?
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
Which element Mo Se Na or Br contains the most moles of atoms in a 1.0 gram sample?
The element with the most moles of atoms in a 1.0 gram sample would be Mo (Molybdenum) as it has the highest molar mass among the given elements (95.94 g/mol). This means that 1.0 gram of Mo would contain the most moles of atoms compared to Se (Selenium), Na (Sodium), and Br (Bromine).

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?
The sample of Al that contains 8.18E+23 atoms has more atoms than a 5.16 mole sample of S. This is because one mole of any substance contains Avogadro's number of atoms or molecules, which is approximately 6.022 x 10^23. Since the Al sample has more atoms than this, it contains the greater number of atoms.
How many moles of N2O molecules are present in a sample that contains 5.23 moles of nitrogen atoms?
Since each N2O molecule contains 2 nitrogen atoms, the number of moles of N2O molecules would be half of the moles of nitrogen atoms. Therefore, in this case, there would be 2.615 moles of N2O molecules present in the sample.
How many moles of fluorine atoms are in a sample of fluorine that contains 7.45 x 1024 fluorine atoms?
Whatever be the substance the one gram mole of that substance would have 6.023 x 1023 atoms or molecules or ions in it. Hence to get the mole just divide the number given by 6.023 x 1023
How many moles of carbon atoms can be obtained from the decomposition of C6H6 in a 1.68 moles sample?
Each molecule of C6H6 contains 6 carbon atoms, so when 1 mole of C6H6 decomposes, 6 moles of carbon atoms are obtained. Therefore, in a 1.68 mole sample of C6H6, 6 × 1.68 = 10.08 moles of carbon atoms can be obtained from the decomposition.
How many moles of phosphorus atoms are in a 100 g sample of phosphorus?
The molar mass of phosphorus is approximately 31 g/mol. To find the number of moles in a 100 g sample, divide the mass by the molar mass: 100 g / 31 g/mol = 3.23 mol. Therefore, there are approximately 3.23 moles of phosphorus atoms in a 100 g sample of phosphorus.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many moles of P are there in a sample of P that contains 3.78E plus 24 atoms?

A sample of Se weighs 20.5 grams will a sample of V that contains the same number of atoms weigh more or less than 20.5 grams?
A sample of V containing the same number of atoms as Se will weigh more than 20.5 grams because vanadium (V) has a higher atomic mass than selenium (Se). The atomic mass of an element will affect the weight of a sample containing the same number of atoms.
