Question

ons 69% HQ10.48 Gaseous sulfur dioxide, a component of acid rain, is made as a product of the combustion of sulfur-containing fuels. Calculate the volume of sulfur dioxide produced at 22.4 "C and 0925 atm by the combustion of 8902 g of fuel that contains 555% of sulfur by mass. Sg(s) + 802(g)8SO2(g) Numeric Answer Unanswered Assigned as 10.49 Heating a 6.582 g sample of an ore containing a metal sulfide, in the presence of excess oxygen, produces 1.459 L of dry SOp, at 48.2 'C and 753.2 to. Calculate the percent by mass of sulfur in the ore Assume that all sulfur in the sample was converted to so, ss-02() sor(s) ALIENWARE

Explanation / Answer

Ans 10.48

Mass of sulfur present = ( 5.55 x 8902) / 100 = 494.061 g

Number of moles of S8 = 494.061 / 256.48

= 1.926 moles

So number of moles of SO2 produced = 8 x 1.926 = 15.4 moles

Volume can be calculated using the formula , pV = nRT

T = 22.4 + 273.15 = 295.55 K

So putting all the valuew we get :

0.925 x V = 15.4 x 0.0821 x 295.55

V = 403.9 L
