Assuming butane undergoes complete combustion in 1 mole of oxygen, 8/13 moles of carbon dioxide and 10/13 moles of water are formed.
Mole Ratio
The number of water molecules obtained is 120,44281714.10e23.
10 moles of nitrogen dioxide are needed to react with 5,0 moles of water.
Only when 5.5 mole O2 react with 11 mole H2, then 11 mole H2O are formed.
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.

According to this balanced equation:Na2O + H2O --> 2NaOH42 moles Na2O react with 42 moles H2O
for each mole of anything there is 6.022x10^23 molecules. Therefore for 5 moles of water there is 5 x 6.022x10^23 = 3.011x10^24 molecules of water
Ca + 2 H2O ------> Ca(OH)2 + H2 so 2 moles of calcium react with 4 moles of water.
Assuming butane undergoes complete combustion in 1 mole of oxygen, 8/13 moles of carbon dioxide and 10/13 moles of water are formed.
when 2 molecules of hydrogen gas and one molecule of oxygen react with each other then they form water(H2O)
A number of atoms/molecules in a given number of moles is regardless of the substance unless it deals with stoicheometry. One mole represents a number of Avogadro's constant, approximately 6.022 x 10^23. Therefore there are 1.91 x 10^25 molecules of water in 31.8 moles.
