44 moles of atoms
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
4.2 moles of CS2 contain 8,4 moles sulfur.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
One molecule has four H atoms.So two moles have 8 moles
44 moles of atoms
If the chlorine is in its normal state of diatomic molecules, there are 16.0 moles of chlorine atoms in 8.00 moles of chlorine. The number of atoms is then 16 times Avogadro's number = 9.64 X 1024, to the justified number of significant digits.
3KNO3, so 9 oxygen atoms.
0,2 moles contain approx. 1,2.10e+23 atoms, molecules etc.
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
2,2 moles of plutonium: 13,248711938.1023 atoms.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
The number of atoms in 1,2 moles of pure aluminum is 7,2265690284.1023.
The total number of atoms in 3.5 moles of calcium is 21,0774929995.10e23.
one mole of oxygen = 16grams and is 6.02x10^23 atoms one milligram of oxygen is 0.001 grams. number of moles = mass used/ RMM of compound therefore number of moles = 0.001/16 =6.25x10^-5 moles used. to convert to number of atoms multiply by avagadros number. 6.25x10^-5 * 6.02x10^23 3.763x10^19 atoms
4.2 moles of CS2 contain 8,4 moles sulfur.
By using Avagadro's constant NA = 6.02 x 1023 Avagadros constant gives the number of atoms which are present within a mole of a substance. so say we have 2 moles then we would have 2 x 6.02 x 1023 = 1.204 x 1024 atoms present.
