How many atoms are there in 2 moles of hydrogen?

Answer 1

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.

Answer 2

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!

Answer 3

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.

Answer 4

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.

Answer 5

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

Answer 6

3 atoms per molecule so 3 x 2 x 6.022 x 1023 = 3.6132 x 1024

Answer 7

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

Answer 8

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
