3.24 X 10^23 atom Ba (1mol Ba/6.022 X 10^23 ) = 0.538 moles
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
No. It is represented by an e- :)
The mass of a single atom would be the mass of one mole of that element, divided by Avogadros number. So for example calcium, Ca, would be 40/6.02214129×1023 mol−1
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.
The answer is 1/12,044.10e23.
moles = mass / molar mass assuming that sulfur is simply represented by "S", then the molar mass is 32.07, as seen in the periodic table (meaning that each sulfur atom is 32.07 grams per mole. so moles of sulfur = 80.25 / 32.07 = 2.50 moles

The number of moles is 18.56.
0,17 moles of stronium is equal to 1,02376394569.10e23 atoms.
PPM describes the amount of a substance in a sample. For example: If you have one million pounds of goo that is 1 part per million (PPM) GOLD, you would have one pound of gold in the million total pounds of goo. PPM is typically used to define how much of a pollutant is in a sample of air. If the sample was determined to be 6 ppm hydrocarbon in a sample, that would mean that of the million moles of the sample of air (the weight of the atoms that make up the sample) there would be 6 moles of the hydrocarbon specified, which, depending on the complexity of the hydrocarbon, could end up being one atom of the hydrocarbon in the sample.
0,688 g calcium is equivalent to 0,017 moles.
The answer is 1/12,044.10e23.
