64 grams sulfur (1 mole S/32.07 grams)(6.022 X 1023/1 mole S) = 1.2 X 1024 atoms of sulfur ====================
It is 32.06 grams.
Sulfur has relative atomic mass of 32 and oxygen have that of 16. The molar mass of sulfur dioxide is 64 grams per mole. Therefore there is approximately 0.58 moles (37.14/64) of sulfur dioxide in given weight.
1.40 kg is equal to 1.40 / 0.03418= 40.96 mole H2S, thus 40.96 mole of S (sulfur) which is 40.96 * 0.03207= 1.31 mole S(0.03418 and 0.03207 are molar masses of H2S and S respectively in kg/mol)
One definition of a mole is the sum of the average atomic weights (mass) of a compound. In this case 2 Copper + 1 Sulfur = (2 * 63.55) + (1 * 32.07) = 159.17 grams per mole. So 22 g / 159.17 g/mole = 0.14 mole of Cu2S
1 mole of sulfur contains 32.065g of sulfur.Source: Periodic table of elements.
Sulfur Trioxide has a molar mass of 80.0632 grams per mole. Therefore, 6.11 moles of Sulfur Trioxide is 489.186152 grams (without significant figures). With significant figures that would be 489 grams.
48.0 grams sulfur (1 mole S/32.07 grams)(6.022 X 10^23/1 mole S) = 9.01 X 10^23 atoms of sulfur
72.0 grams sulfur (1 mole S/32.07 grams)(6.022 X 10^23/1 mole S) = 1.35 X 10^24 atoms of sulfur
Full formal set up. 48.096 grams sulfur (1 mole S/32.07 grams)(6.022 X 1023/1 mole S)(1 mole S atoms/6.022 X 1023) = 1.4997 moles of sulfur atoms ---------------------------------------
The molecular weight of 1 mole of sulfur is 32 amu or grams.
