HOW MANYMOLES OF SULFUR DIOXIDE CAN BE PRODUCED FROM 20.0G OF HYDROGEN SULFIDE?

1 answer

H2S ==> SO2
mols H2S = 20.0g/molar mass = approx 0.6 but you need to do it more accurately.
There is 1 mol S in H2S and 1 mol S in SO2; therefore, you should be able to produce 0.6 mols SO2.
Then g = mols x molar mass.
Remember to do the math yourself because 0.6 is an estimate.
