Find the moles of sulfur produced, if 2.5 moles of sulfur
dioxide are used in the following chemical reaction.
SO2 + 2H2S + 2H2O + 3S
a 7.5 mol

Answer 1

7.5mols of S

Step-by-step explanation:

just make sure your equation is balanced, and in this case it's balanced,

so now you can do more to more ratio.

so in this case we are dealing with SO2 and S.

According to our balanced equation we have 1 mol of SO2 producing 3mols of S, i.e

1mol(SO2). : 3mols(S)

we've been asked that if we use 2.5 moles of SO2, how many moles of S will be produced?

So, this is how we can determine the number of moles of S that will be produced .

SO2 : S

1mol : 3mols(S)

2.5mols: x

we cross multiply

x=2.5×3

x=7.5mols of S.

.: if we use 2.5 mols of SO2,, 7.5mols of Sulfur will be produced
