C2H3NO could be either methyl isocyanate or glycolonitrile. They both share this molecular formula, through their structures are different. Since there are a total of 7 atoms in one molecule of C2H3NO, 4 moles of C2H3NO would have 28 moles of atoms.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
0.180 moles C(OH)4 (4 moles H/1 mole C(OH)4)(6.022 X 10^23/1 mole H) = 4.34 X 10^23 atoms of hydrogen

each mole has avogadro's number of atoms in it, which is 6.02 x 10 to the 23rd power. so, 4 x 6.02 x 10 23 power of atoms
1 mole of any substance contains 6.02 x 1023 constituent particles, correct to three significant figures (avogadro constant).Number of molecules of 4 moles of MgCl2 = 4 x 6.02 x 1023In every molecule of MgCl2 there are 3 atoms.Thus, number of atoms in 4 moles of MgCl2 = 3 x 4 x 6.02 x 1023 = 7.22 x 1024
44 moles of atoms

4 moles of oxygen atoms are present in 4 moles of H2O
0.4965 moles rounded to 4 significant figures
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
1 mol has 6,022 140 857.10e23 atoms (The number of Avogadro).4 moles of sodium have 24,088 563 428.10e23 atoms.
The answer is 4 moles.
Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus

The mass of 4 moles of fluorine F atoms is 151,98 g (because fluorine is a diatomic element).
The molecular formula for sulfuric acid is H2SO4. This shows that each molecule contains exactly 4 oxygen atoms. Therefore, 0.750/4 or 0.1875 moles of sulfuric acid contain 0.750 moles of oxygen atoms.
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
