By definition, there are 6.02 x 1023 molecules of a substance in one mole of the substance - this is Avogaddro's number. Therefore, in 8 moles of oxygen (O2) there would be 4.816 x 1024 molecules of oxygen. As there are 2 atoms in each molecule, you would have 9.632 x 1023 atoms of oxygen.

How many moles of carbon are in 5.62 atoms of carbon?
There are 9.33 moles of carbon in 5.62 atoms of carbon.
How many moles of electrons are gained when three moles of oxygen atoms are reduced to oxide ions?
When three moles of oxygen atoms (O) are reduced to oxide ions (O²⁻), each oxygen atom gains two electrons. Therefore, for three moles of oxygen atoms, the total number of moles of electrons gained is 3 moles of O × 2 moles of electrons per mole of O, which equals 6 moles of electrons. Thus, 6 moles of electrons are gained in this reduction process.
How many atoms are present in 16 g of o and 8 g of s?
To find the number of atoms in 16 g of oxygen (O) and 8 g of sulfur (S), we first calculate the moles of each element. The molar mass of oxygen is approximately 16 g/mol, so 16 g of O contains 1 mole, which equals (6.022 \times 10^{23}) atoms. The molar mass of sulfur is about 32 g/mol, so 8 g of S contains 0.25 moles, which equals (1.5055 \times 10^{23}) atoms. In total, there are approximately (7.527 \times 10^{23}) atoms (1 mole of O + 0.25 moles of S).
How many moles of atoms are in 4.1 x 10-12g O?
To find the number of moles of atoms in 4.1 x 10^(-12) g of oxygen, you first convert the mass to moles by dividing by the molar mass of oxygen (16 g/mol). 4.1 x 10^(-12) g / 16 g/mol = 2.56 x 10^(-13) moles of oxygen atoms.

How many moles does a sample of CO2 that contains 8.16x1022 O atoms?
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

Three moles of N2O4 contains six moles of nitrogen atoms (N) and twelve moles of oxygen atoms (O), since each molecule of N2O4 consists of two nitrogen atoms and four oxygen atoms. Therefore, in total, there are 18 atoms in three moles of N2O4.
How many moles of O atoms are present in a 254g sample of carbon dioxide?
To find the number of moles of oxygen atoms in a 254 g sample of carbon dioxide (CO₂), first calculate the molar mass of CO₂, which is approximately 44 g/mol (12 g/mol for carbon and 32 g/mol for two oxygen atoms). The number of moles of CO₂ in the sample is 254 g ÷ 44 g/mol = about 5.77 moles. Since each molecule of CO₂ contains two oxygen atoms, the total number of moles of oxygen atoms is 5.77 moles × 2 = approximately 11.54 moles of O atoms.
