Lithium Sulfate Li2SO4 has 4 oxygen atoms per molecule.
There are 4 atoms - three lithium (Li) atoms and one phosphorus (P) atom.
4H2SO4 = 4*(2(H)+1(S)+4(O)) = 4*(2+1+4) = 4*7 = 28 There are 28 atoms in 4 moles of H2SO4.
1 mole of iron atoms has the greatest mass - 55,845 g.
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
The answer is 1,668.10-4 moles.
12 moles Li
44 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
1 mol has 6,022 140 857.10e23 atoms (The number of Avogadro).4 moles of sodium have 24,088 563 428.10e23 atoms.
