There are approx 6.02 X 1024 oxygen atoms.
--> 5mol CO2 (2mol O2/ 1mol CO2)= 10 mol O2
Then Avagadro's number is used to calculate the number of atoms....
10 mol O2 (6.02 X 1023/ 1mol) = 6.02 X 1024
1,4.10e23 molecules
Given: 7.6 x 1024 O2 moleculesKnown: 1 mole O2 molecules = 6.022 x 1023 molecules O2 moleculesConvert molecules to moles.7.6 x 1024 molecules O2 x (1mol O2/6.022 x 1023 molecules O2) = 13 moles O2 (rounded to two significant figures)
First, calculate the molar mass of O2 (molecular weight = 32 g/mol). Then, convert the given number of molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol). The result would be approximately 0.067 moles of O2.
In the balanced chemical equation for the reaction of carbon (C) with oxygen (O2) to form carbon dioxide (CO2), one molecule of carbon reacts with one molecule of O2 to form one molecule of CO2. Therefore, to form 14 molecules of CO2, 14 molecules of O2 will react with 14 molecules of carbon, containing a total of 14 carbon atoms.
Pyruvate and O2
O2 has 2 atoms of oxygen.
There are (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
Titanium dioxide (TiO2) contains no molecules of O2. It is composed of one titanium atom and two oxygen atoms in each molecule, but does not contain any molecules of molecular oxygen (O2).
1,4.10e23 molecules
The number of oxygen atoms is 0,188.10e23.
If 2 O is O2: one molecule.
Given: 7.6 x 1024 O2 moleculesKnown: 1 mole O2 molecules = 6.022 x 1023 molecules O2 moleculesConvert molecules to moles.7.6 x 1024 molecules O2 x (1mol O2/6.022 x 1023 molecules O2) = 13 moles O2 (rounded to two significant figures)
To find the number of molecules, first calculate the amount of O2 in moles using the ideal gas law. Then use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
1 mole O2 weighs 32 gso 64 g O2 is 2 mol O2 gaswhich has 2 X 6.022 X 1023 = 1.2066 X 1024 molecules of O2
1 mole of O2 has 6.023 x 1023 molecules. So, 23 moles of O2 will have 23 x 6.023 x 1023 molecules or 138.53 x 1023 molecules.
The number of moles is 166,666.10e-11 (if you think to billion as 10e9).
The number of molecules is 7,2265690284.10e23.
