multiply that by avagadros number. 6.02x10^23
The number of molecules in 1.5 moles of water is 9,033.10e23.
27.10e23 atoms
4.5*10^23
9.033x1023
4 moles of oxygen atoms are present in 4 moles of H2O
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
H2O is water. One mole of water contains 2 moles of hydrogen atoms. Therefore, 10.7 moles of water contain 21.4 moles of hydrogen atom.
Two: Hydrogen and 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====================
4 moles of oxygen atoms are present in 4 moles of H2O
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
6.49 moles of water
H2O or water doesn't have any helium in it.
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
H2O is water. One mole of water contains 2 moles of hydrogen atoms. Therefore, 10.7 moles of water contain 21.4 moles of hydrogen atom.
It forms H2O when burned.There are 3.744 moles of H2O after burned.
3.2 moles of water (H2O)
2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------
Two: Hydrogen and 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====================
According to this balanced equation:Na2O + H2O --> 2NaOH42 moles Na2O react with 42 moles H2O
