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.
There are 9.33 moles of carbon in 5.62 atoms of carbon.
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.
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.
The answer is 0,068 mol (for O not for O2).
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.
1 mole of Li₂O contains 2 moles of lithium (Li) atoms and 1 mole of oxygen (O) atoms. Therefore, in 1 mole of Li₂O, there are a total of 3 moles of atoms.
There are 9.33 moles of carbon in 5.62 atoms of carbon.
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
In 0.800 moles of MgO, there are the same number of oxygen atoms as there are in 0.800 moles of O atoms. One mole of MgO contains one mole of oxygen atoms, which is equivalent to 6.022 x 10^23 oxygen atoms.
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.
The answer is 0,068 mol (for O not for O2).
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms
One molecule of N2O N 2 O contains one atom of oxygen.
5 moles H2O (1 mole O/1 mole H2O)(6.022 X 1023/1 mole O)(1 mole O atoms/6.022 X 1023)= 5 moles oxygen atoms=================( as you see this is a formal set up that you do not need to use fully as Avogadro's number is over itself as a form of one )5 moles H2O (2 moles H/1 mole H2O)6.022 X 1023/1 mole H)(1 mole H atoms/6.022 X 1023)= 10 moles hydrogen atoms====================
2 x O3 = 6 of O so 6 x 6.023 x 1023 = 3.6138 x 1024
3.70 moles NaClO4 (4 moles O/1 mole NaClO4) = 14.8 moles oxygen
In diphosphorous pentoxide (P4O10), there are 10 oxygen atoms for every molecule. Therefore, in 5.00 moles of diphosphorous pentoxide, there would be 5.00 moles x 10 oxygen atoms = 50.0 moles of oxygen atoms.
