The following balanced equation shows the formation of sulfur dioxide. s + o2 mc023-1.jpg so2 how many moles of sulfur are needed to produce 15.0 mol of sulfur dioxide?

S  +  O₂   →   SO₂

The mole ratio of S to SO₂ is 1 : 1
∴ if moles of SO₂ = 15
 then moles of SO₂ = 15 mol

∴ the # of moles of sulfur needed to produce 15.0 mol of sulfur dioxide is 15 mol

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
