How many liters of SO₃(g)are produced at 25°C and 1.00 atm from the combustion of 1.00 kg of coal which is 1.00% S by weight? Assume all the sulfur in the coal ends up as SO₃. A)0.640 L B)5.08 L C)7.63 L D)11.4 L

1.00 kg of coal contains 10 g of sulfur (1.00% of 1.00 kg). The molar mass of sulfur (S) is 32.07 g/mol, so there are 0.312 mol of sulfur. The reaction S + O2 → SO3 shows a 1:1 molar ratio, so 0.312 mol of SO3 is produced. Using the ideal gas law at 25°C (298 K) and 1 atm, the volume is calculated as V = nRT/P = (0.312 mol)(0.0821 L·atm/mol·K)(298 K)/(1 atm) = 7.63 L.
