1 of anything is 1.6605E-24 moles of that type of thing, no matter what it is (e.g. a quark, an electron, an atom, a molecule, an egg, a person, a planet, a galaxy).
The mole is a unitless number similar in concept to the dozen (12 things) or the gross (144 things), except it is a much larger value (6.0221E23 things).
The answer is 1/12,044.10e23.
The number of moles of calcium carbonate are 3.5 moles. , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.
it wouldn't be moles of Cl it would be Cl2 as chlorine doesn't exist as an atom it exsists as two joined to form a compound this is very easy stuff the answer is 15 moles of Cl2 as there 30 moles of Cl hope this helps learn your moles it's easy stuff
3.24 X 10^23 atom Ba (1mol Ba/6.022 X 10^23 ) = 0.538 moles
It depends on the substance. Remember that moles are a unit of amount, and one mole is 6.02 × 1023 atoms. So if you have lead and hydrogen, they are obviously going to weigh differently. It would take far fewer atoms of lead to amount to 1 gram; therefore, less moles. However, one hydrogen atom has far less mass than one lead atom, and would need more atoms (and moles) to make one gram.

The number of moles of calcium carbonate are 3.5 moles. , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.
1 atom-gram of uranium = 238,02891 grams

9.00 moles carbon (6.022 X 1023/1 mole carbon)(6 electrons/1 atom carbon) = 3.25 X 1025 electrons in 9.00 moles carbon ============================
0,17 moles of stronium is equal to 1,02376394569.10e23 atoms.
The number of moles is 18.56.
4.2 moles of CS2 contain 8,4 moles sulfur.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.
Since quinine has a nitrogen atom in its chemical formula, 1 mole of quinine contains 1 mole of nitrogen atoms. Therefore, in 2.5 x 10^-2 moles of quinine, there are also 2.5 x 10^-2 moles of nitrogen atoms.
0,688 g calcium is equivalent to 0,017 moles.
