Question

A coal source contains 1.0% sulfur by mass.

Part A

If 1.5×104 kg of coal is burned and forms oxides, calculate the mass of CaSO4(s) that is produced from "scrubbing" the SO2 pollutant out of the exhaust gas. Assume that all of the sulfur in the coal is converted to calcium sulfate.

Express your answer using two significant figures.

A coal source contains 1.0% sulfur by mass.

Part A

If 1.5×104 kg of coal is burned and forms oxides, calculate the mass of CaSO4(s) that is produced from "scrubbing" the SO2 pollutant out of the exhaust gas. Assume that all of the sulfur in the coal is converted to calcium sulfate.

Express your answer using two significant figures.

Explanation / Answer

mass of sulfur = (1.4*10^4)*1/100 = 140 kg

No of mol of S = (140*10^3)/32 =4375 mol

No of mol of so2 = 4375 mol

No of mol of CaSO4 produced   = 4375 mol

mass of caso4 produced = 4375*136.14 = 595.6125 kg

     = 6.0*10^2 kg
