H2O consists of two Hydrogen and one Oxygen. Three sets of these would mean 9 atoms in your three molecules of water.
There are three
divide this number by avagadros number to get moles. (5.16x1024)/(6.02x1023)=8.57mol of H2O as there are 3 atoms in each molecule there are 3x8.57=25.7 moles of atoms.
The notation "3 CO2" indicates that there are three molecules of carbon dioxide (CO2). Therefore, in 3 CO2, there are exactly three molecules of CO2 present. Each molecule consists of one carbon atom and two oxygen atoms, but the question specifically asks about the number of molecules.
During the Calvin cycle, one molecule of 3-phosphoglycerate (3-PGA) is produced for every carbon dioxide molecule fixed. Thus, the number of 3-PGA molecules present during the Calvin cycle depends on the number of carbon dioxide molecules fixed in the process.
The reaction is :- 2C2H6 + 7O2 ----------> 4CO2 + 6H2O When one mole ethane is combusted 7/2 moles of oxygen are used. When 3 moles of ethane are combusted 3 x 7/2 moles of oxygen used. No. of oxygen molecules consumed =6.022 x 1023 x7/2= 21.077 x 1023=2.107 x 1024 molecules.
3 total - 2 Hydrogen & 1 Oxygen Hence H20

Yes O2 O-O ---------------------------------------- Water is however H20 H-O-H Which is 3 molocules ---------------------------------------
There are Avogadro's number of molecules present in one mole of any substance. For C3H4, the molecules in one mole would be equal to Avogadro's number multiplied by 3 (for 3 carbon atoms) plus 4 (for 4 hydrogen atoms), which equals 3 * 6.022 x 10^23 + 4 * 6.022 x 10^23 = 26.056 x 10^23 molecules.
The notation "3 CO2" indicates that there are three molecules of carbon dioxide (CO2). Therefore, in 3 CO2, there are exactly three molecules of CO2 present. Each molecule consists of one carbon atom and two oxygen atoms, but the question specifically asks about the number of molecules.
The total number of atoms of the reactants should be equal to the total number of atoms of the products. The total number of molecules of the reactants should be equal to the total numbers of molecules of the products
H20
No one.
It is not possible to determine the number of molecules in 3 grams of nail without knowing the chemical composition of the nail. The number of molecules present would depend on the elements and compounds that make up the nail.
During the Calvin cycle, one molecule of 3-phosphoglycerate (3-PGA) is produced for every carbon dioxide molecule fixed. Thus, the number of 3-PGA molecules present during the Calvin cycle depends on the number of carbon dioxide molecules fixed in the process.
If you are in England you can watch h20 just add water on nickelodeon or you can watch it in youtube just tipe down h20 just add water season 3
