Exactly the same as the length in a length of string.
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
5 moles of sulfur is equal to 160,3 g.
one mole contains 6.022 x 10^23 atoms. so multiply by 32
28 mass of oxygen
Grams is a unit of weight, miles is a unit of distance. There's no comparison between the two.

How many moles of sulphur in 1.81 X 1024 atoms of sulphur ? The answer is 3. The fact that we are talking about sulphur is immaterial. A mole is just another name for a gram molecular weight. The number of atoms in a gmw (mole) is given by Avogadro's Number, which is 6 X 1023 no matter what the element.
one mole contains 6.022 x 10^23 atoms. so multiply by 32
Divide mass of 128 g SO2 by its molar mass of 64.066 g.mol−1 SO2 and you get the number of moles: 1.9979 = 2.00 mole SO2

Any
no. moles = mass / molecular weight molecular weight = 64.06 mass = 28.4 28.4 / 64.06 = .4433moles sulphur
28 mass of oxygen
Grams is a unit of weight, miles is a unit of distance. There's no comparison between the two.
20 moles x 6.02x10^23 atoms/mole = 1.2x10^25 atoms
2 mole S8 (8 mole sulfur/1 mole S8)(6.022 X 1023/1 mole sulfur) = 9.6 X 1024 atoms of sulfur --------------------------------------- Same as any atom ratio in a compound, moles of atoms over moles of the compound times Avogadro's number.
