In 1 mole of anything there is 6.022 x 10^23 of that item.
In 1 mole of chairs there is 6.022 x10^23 chairs.
In 1 mole of bacteria there is 6.022 x 10^23 bacteria.
Likewise, 1 mole of hydrogen atoms is equivalent to 6.022x10^23 hydrogen atoms.
2 moles of hydrogen atoms is double this amount.
2 x 6.022 x 10^23 = 12.044 x 10^23, which is 1.2044 x 10^24 hydrogen atoms.
This number, 6.022 x 10^23, is called Avogadro's Number. It is like the word "dozen", which means "12 of". 1 dozen bagels is 12 bagels. 1 dozen animals is 12 animals. Same concept here. Hope that helps ya.
17.32 moles H2O (2 moles H/1 mole H2O) = 34.64 moles hydrogen
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
I was wondering about this... but I think if you combined..The four oxygen gas O2, and the two of Hydrogen gas H2.. and predict was will happened I guess this is what it will or might be calculate, but Im not sure.KKKO2O2+H2H1O4+H2O2H
First, calculate the total weight of hydrogen in 1.5 lb of hydrogen peroxide: 1.5 lb * 454 g/lb * 0.0593 = 128.97 g of H2O2 Then, convert this weight to the number of moles of hydrogen: 128.97 g / 34.0147 g/mol = 3.79 moles of H2O2 Since each mole of H2O2 has 2 moles of hydrogen atoms, there are 3.79 * 2 = 7.58 moles of hydrogen atoms. Finally, calculate the number of atoms: 7.58 moles * 6.022 x 10^23 atoms/mol = 4.56 x 10^24 atoms of hydrogen.
N2 + 3H2 -----> 2NH3 so 3 moles of hydrogen produce 2 moles of ammonia. Therefore 12.0 moles of hydrogen will produce 8 moles of ammonia.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
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.
One molecule has four H atoms.So two moles have 8 moles
2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------
2.5 moles H2O (2 moles H/1 mole H2O) = 5 moles of hydrogen
Just moles against the ratio of hydrogen atoms in compound then against Avogadro's number. Like this 0.09 moles H2SO4 (2 moles H/1 mole H2SO4)(6.022 X 10^23/1 mole H) = 1.1 X 10^23 hydrogen atoms
We have 2.1 moles of H3PO4 However , there are three hydrogen atoms. So this makes for 3 x 2.1 = 6.3 moles of hydrogen atoms. Further, hydrogen exists as the diatomic molecule 'H2'. So a 'free' hydrogen molecules of H2 we have 6.3 / 2 = 3.15 moles(H2)
In 2 moles of hydrochloric acid (HCl), there are 2 moles of hydrogen atoms. Since each molecule of HCl contains one hydrogen atom, multiplying the moles of HCl by Avogadro's number (6.022 x 10^23) gives the number of hydrogen atoms. Therefore, there are 1.204 x 10^24 hydrogen atoms in 2 moles of HCl.
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.
In 5 moles of octane, C8H18, there are 40 moles of carbon atoms (5 moles octane x 8 carbon atoms) and 90 moles of hydrogen atoms (5 moles octane x 18 hydrogen atoms).
