Sulfuric acid has a molecualr weight of 98 and so 2.5 moles would weigh 245 g
As molar mass of sulfur is 32 g/mol, the mass of 2.5 moles is equal to 80 g.
From the periodic table, calcium has a molar mass of 40.078g/mol and sulfur has a molar mass of 32.065g/mol. The formula for compound formed from calcium and sulfur, calcium sulfide is CaS. The molar mass of CaS is 72.143. So, if you round the numbers, 40g of Ca + 32g of S will produce 72g of CaS.
convert to mol, (divide by molar mass) then multiply by 22.4
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
Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
The cost of sulfur per gram is 0.50 because its cost is 500 per kilogram, or 1000 grams. Sulfur is a non-metal with the atomic number of 16.
= 0.75 mol x 32 g.mol-1 = 24 g
