Answer:
952.2g SO3
Explanation:
Molar mass of C4H8S2 is 120.2363 g/mol
Mol in 750.0g = 750.0/120.2363 = 6.238 mol
1mol C4H8S2 produces 2 mol SO3
6.238 mol will produce 2Ă—6.238 = 12.476 mol SO3
Molar mass SO3 = 32+3Ă—16 = 80.0g/mol
Theoretical yield = 12.476Ă—80.0 = 998.08g
The actual yield is 95.4%
Actual mass-produced = 95.4/100Ă—998.08 = 952.2g SO3 produced
