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.
each mole of h2o molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. Therefore, three moles of atoms make up one mole of hydrogen molecules. And, six moles of atoms make up 2 moles of h2o. There are 6.023E23 atoms in a mole. So, six moles of atoms is equal to 6(6.023E23) or 3.614E24 atoms Wouldn't that be 36.14? More precisely a mole is simply a term that denotes a particular quantity. Just as a dozen equals 12 of something a mole is a specific quantity of atoms a dozen trucks or a dozen cotton balls still equal 12 of each. So to it is with a mole. A mole is 6.0221367 X 10^23, or 6.0221367E23. To put that as a number most people recognize you take 6.0221367 and move the decimal point 23 places to the right. That makes a mole equal to 602,213,670,000,000,000,000,000 which, don't quote me, lol, I believe is in the sextillions. Whatever it is it is an extremely large number! People can sometimes get confused at this next step. Your question asked how many "atoms" are present in 2 mole of H2O. H2O is a molecule, the sum of 2 Hydrogen atoms and 1 oxygen atom. To draw a parallel think of it like this: how many tires are there in 2 dozen vehicles? It takes 4 tires per vehicle and 2 dozen cars are 24. 24 X 4 = 96. Same logic applies here because it requires 3 atoms to make one water molecule. 2 mole of water molecules are simple to equate. It is 6.0221367 X 10^23 multiplied by 2. 3 atoms per molecule so as the original respondent stated there are 4 mole of Hydrogen atoms and 2 mole of Oxygen atoms in 2 mole of water molecules. That number, hold on to your hat, is 3.61328202 X 10^24 or 3,613,282,020,000,000,000,000,000 and I believe that is Three Septillion Six Hundred Thirteen Sextillion Two Hundred Eighty Two Pentillion Twenty Quadrillion. Which is alot, alot, alot, alot, lot, lot, lot, lot, lot!
A mole is a number which can be expressed in scientific notation, like so: 6.022*10^23, or expanded, like so: 602,200,000,000,000,000,000,000. Water, or H2O, consists of three atoms, one of oxygen and two of hydrogen. If you have two moles of this, then one must multiply 3 by 2 mol, giving the number 1.8066*10^24.
In each molecule of water there is one hydrogen atom. In 2.69 moles, there are 8.124 E23 molecules, so there are the same number of atoms of hydrogen present.
First u need to find # of molecules in 1 mole.
Second multiply it by 2
Third u need to multiply it by 3 because 1 molecule has 3 atoms.
3(2(6.02E23))
=3.612E24
3 atoms per molecule so 3 x 2 x 6.022 x 1023 = 3.6132 x 1024
2.70 moles water (2 mole H/1 mole H2O)(6.022 X 10^23/1 mole H)
= 3.25 X 10^24 atoms of hydrogen
2.60 moles H2O (2 moles H/1 mole H2O)(6.022 X 10^23/1 mole H)
= 3.13 X 10^24 atoms of hydrogen
1 molecule of hydrogen contains 2 hydrogen atoms,so 1 mole of hydrogen consists of 2 moles of atoms.
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
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.
17.32 moles H2O (2 moles H/1 mole H2O) = 34.64 moles hydrogen
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
1 molecule of hydrogen contains 2 hydrogen atoms,so 1 mole of hydrogen consists of 2 moles of atoms.
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
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.
4 moles of hydrogen atoms
One molecule has four H atoms.So two moles have 8 moles
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
Glucose is C6H12O6 and thus the mole ratio is 6 moles of carbon to 6 moles of Hydrogen Molecules (12 moles of Hydrogen atoms) and 3 moles of oxygen molecules (6 moles of oxygen atoms)
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.
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
The molar mass of hydrogen is 2.
There are no moles.There are 2 atoms in one molecule.
