4.2 moles of CS2 contain 8,4 moles sulfur.

0.010 moles The molar mass of H2SO4 is 98.1 grams per mole. To find out how many moles are present in a given mass, divide the mass by the molar mass. So: 1g/98.1g mol-1 is 0.010 mol.
7.71 grams sulfur (1 mole S/32.07 grams) = 0.2404 moles of sulfur
No. of moles=given mass/gram molecular mass =16/16 =1

how many moles of sulfur are present in 3.4 moles of Al2(SO4)3
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
The way to work this is out is to first find the mass of one mole of H2SO4 .(98.08 grams). 10 grams is therefore 10/98.08 moles- = 0.102 moles of sulfuric acidEach mole of sulfuric acid contains gram atom of sulfur so we have .102 moles sulfur..if you want the actual count of atoms multiply by avogadros number which is6.0221415 × 1023 (most teachers will accept using 6.022 instead of the longer version)
Simply divide by the number that signifies moles of any thing; Avogadro's number. 3.4 X 10^23/6.022 X 10^23 = 0.56 moles of H2SO4
53,7 grams of sulfur is equivalent to 1,675 moles.
3,2x10e22 atoms of sulfur is equivalent to 0,053 moles.
300 g sulfur is equivalent to 9,357 moles.
