From the Periodic Table, Argon has an atomic weight of 39.948. One mole of any element is equal to its atomic weight in grams. So 1 mole of Ar = 39.948g of Ar.
Using that equality, you do the following calculation to find the number of moles of Ar in 22g of Ar:
22g Ar X 1mol Ar/39.948g Ar = 0.55mol Ar

The atoms in 3.2 moles O2 Could be other things, I guess, but I will do these two. 3.2 moles O2 (32 grams/1 mole O2) = 102.4 grams of gaseous oxygen -------------------------------------------- 3.2 mole O2 (6.022 X 1023/1 mole O2) = 1.9 X 1024 atoms of gaseous oxygen --------------------------------------------------
Approximately how many moles are in 300 grams of sulfur?
To determine the number of moles in 300 grams of sulfur, you need to know the molar mass of sulfur. The molar mass of sulfur is 32.06 g/mol. You can calculate the number of moles by dividing the given mass by the molar mass: 300 g / 32.06 g/mol ≈ 9.35 moles.
What mass of oxygen gas contains the same number of moles as 56 gram of Sulphur?
To determine the mass of oxygen gas containing the same number of moles as 56 grams of sulfur, calculate the molar mass of sulfur (32 g/mol) and use it to find the number of moles in 56 grams. Then, since the molar ratio of sulfur to oxygen in a compound is 1:1, this same number of moles of oxygen gas would weigh 32 grams.
