The molar mass of methane is 16,04 g.1 mol has 6,022 140 857.10e23 molecules. In your question the correct word is molecules not atoms.6,022 140 857.10e23---------------------------------16,04 g4,5.10e24---------------------------------------------------xx = (4,5.10e24 . 16,04)/6,022 140 857.10e23 = 119,6 g
Lithium oxide (Li₂O) consists of two lithium (Li) atoms and one oxygen (O) atom. Therefore, it has a total of three atoms. If you meant a different substance or context, please clarify for a more accurate response.
Five atoms
It depends on how many hydrogens are there and how many oxygen atoms there are.
2 atoms
How many atoms does C8H16O8 have? Please answer need it quick.
Please explain what on earth gaonsl are.
Please explain specifically your question
This question makes no sense. Please explain in more detail.
In 12g of carbon-12, the molar mass of one carbon-12 atom is 12g/mol. This means that 12g of carbon-12 is equivalent to 1 mole of carbon-12 atoms. Avogadro's number states that 1 mole of atoms contains 6.022 x 10^23 atoms. Therefore, there are 6.022 x 10^23 atoms in exactly 12g of carbon-12.
Please explain why this information is important.
Please specify the atom and the molecule. Question cannot be answered without this information.
well, iam not quite sure to be completley honest :'( if you know the answer please edit this and put it please then i can do my sience homework :)

please explain more -which light, and meaning of '04combo1.7'
I'm sorry but your question makes no sense. Please explain what you are referring to.
First multiply 8e-15 by 6.022e23 to get the number of atoms and multiply that by 30 ( the number of hydrogen atoms)
