Avogadro's number is the number of units in one mole of any substance (defined as its molecular/atomic weight in grams), equal to 6.022140857 × 10 23.
Using this we know that because the molecular weight of sulfur is 32.06, a mole of sulfur will weigh 32.06 grams.
100 Hydrogen atoms have an atomic mass of 100.794, 4 Sulfur atoms have an atomic mass of 128.26, and 1 Lanthanum atom has an atomic mass of 138.90547.
no of atoms = weight of the given substance/ atomic mass of substance according to the question:- no of atoms = 3/32 answer

A sulfur molecule has the formula S8. Multiply the number of sulfur atoms (8) times the atomic weight of sulfur in grams (32.065g). The molar mass of S8 = 256.52g S8.
The Atomic Mass of one (1) atom of sulfur is 37.02. The atomic mass of three (3) atoms of sulfur is 96.21. 32.07 * 3 = 96.21

They don't. Sulphur has about twice the atomic mass of oxygen.
A sulfur molecule has the formula S8. Multiply the number of sulfur atoms (8) times the atomic weight of sulfur in grams (32.065g). The molar mass of S8 = 256.52g S8.
I think you meant 3.09x10^24 atoms of sulfur. 3.09x10^24 atoms * (1 mol / 6.02x10^32 atoms) * (32 g / 1mol) = 165 grams
A sulfur dioxide has one sulfur atom and two oxygen atoms. Therefore, considering a mole of sulfur dioxide (64g); there is 32g of sulfur and 32g of oxygen. Hence the mass percent of oxygen is 50%.
To find the number of sulfur atoms in a given mass of sulfur, you can use the following steps: Determine the number of moles of sulfur using the formula: moles = mass molar mass moles= molar mass mass Given that the molar mass of sulfur ( S S) is 32.06 g/mol and the mass ( m m) is 1.56 g: moles = 1.56 g 32.06 g/mol moles= 32.06g/mol 1.56g Once you have the moles of sulfur, you can use Avogadro's number (6.022 x 1 0 23 10 23 mol − 1 −1 ) to find the number of atoms: number of atoms = moles × Avogadro’s number number of atoms=moles×Avogadro’s number Let's calculate it: moles = 1.56 g 32.06 g/mol ≈ 0.0488 mol moles= 32.06g/mol 1.56g ≈0.0488mol number of atoms = 0.0488 mol × ( 6.022 × 1 0 23 mol − 1 ) number of atoms=0.0488mol×(6.022×10 23 mol −1 ) number of atoms ≈ 0.0488 × 6.022 × 1 0 23 number of atoms≈0.0488×6.022×10 23 number of atoms ≈ 3.0 × 1 0 22 number of atoms≈3.0×10 22 Therefore, there are approximately 3.0 × 1 0 22 3.0×10 22 sulfur atoms in 1.56 g of sulfur.
