• Which has more atoms, one gram of hydrogen or one gram of oxygen?

    Best answer: Since Trinity has injected so much misinformation into this simple question, here are the complete calculations: (1 gram H2) / (2.01588 g H2/mol) x (6.022 x 10^23 molecules/mol) x (2 atoms/molecule) = 5.97 × 10^23 atoms H (1 gram O2) / (31.99886 g O2/mol) x (6.022 x 10^23 molecules/mol) x (2 atoms/molecule) =... show more
    Best answer: Since Trinity has injected so much misinformation into this simple question, here are the complete calculations:

    (1 gram H2) / (2.01588 g H2/mol) x (6.022 x 10^23 molecules/mol) x (2 atoms/molecule) = 5.97 × 10^23 atoms H

    (1 gram O2) / (31.99886 g O2/mol) x (6.022 x 10^23 molecules/mol) x (2 atoms/molecule) = 3.76 × 10^22 atoms O

    "5.97 × 10^23 atoms" is more than "3.76 × 10^22 atoms" (by a factor of nearly 16) so there are more hydrogen atoms.

    Although lenovo should get best answer because it was first, and this question should not have needed any calculations at all.

  • If radium combine to radium chloride then compound formed is radioactive or not?

    Best answer: Radioactivity doesn't disappear just because a compound has been formed.

    If it did, all our nuclear waste issues would be solved.

  • Can i fart in a jar and keep the smell for 20 years?

    Best answer: Its just Methane Gas isnt it manufactured by your own body. Sometimes it doesnt smell at all,but it would not last half an hour let alone 20 years,sorry.

  • I am getting confused with amu and grams.?

    Best answer: one ATOM of carbon is 12 amu one MOLE of carbon is 12 grams one mole is approx. 6.022*10^23 atoms and the "rule" (which seems to work for all elements and molecules) is: if you have that number of atoms, then the mass (in gram) is the same number as the number of amu in one atom (or molecule). 1 atom... show more
    Best answer: one ATOM of carbon is 12 amu
    one MOLE of carbon is 12 grams

    one mole is approx. 6.022*10^23 atoms
    and the "rule" (which seems to work for all elements and molecules) is:
    if you have that number of atoms, then the mass (in gram) is the same number as the number of amu in one atom (or molecule).

    1 atom of Xenon is (on average) 131.293 amu
    (in chemistry, we use the weighted average of all stable isotopes found in nature)
    (Xenon has 8 stable isotopes, ranging from 124 amu to 136 amu)
    If you get a mole of Xenon (6.022*10^23 atoms) with the same mix of isotopes as found in nature, then it will have a mass of 131.293 grams

    If, on the other hand, you manage to get a mole of Xenon-129 (where all the atoms of Xenon each have 129 amu), then that mole will only have a mass of 129 grams.

    ---

    Because, in chemistry, we work with average masses most of the time, using the mole (where the set of 6.023*10^23 atoms will normally follow the same mixing ratios as found in nature) allows us to make better calculations to determine inputs and outputs (important for experiments and for industrial planning).

    Balancing equations, for example
    2H2 + O2 --> 2H2O
    is supposed to involve atoms. But for determining quantities (mass), we have to work with moles... and we forget to point that out.
    Therefore, we end up using words like "atom" when we mean mole.
