The reaction for the formation of sulfur trioxide is shown below.
2SO2(g) + O2(g) 2SO3(g)
60 cm3 of sulfur dioxide are mixed with 60 cm3 of oxygen and allowed to reach equilibrium.
What is a possible equilibrium mixture from this reaction?

That is a very strange question, as it isn’t terribly clear what it means by that.

What have you tried so far, and how have you interpreted the question?

I think you need to convert cm3 to dm3 (divide by 1000), and then do that divide by 24 to find the number of moles (as 1 mol of gas occupies 24dm3). From the moles you can work out how much has been lost/gained under equilibrium

Whilst you could do that, I don’t think it would actually help much. It would tell you how many moles of SO2 and O2 there are initially if the gas is kept under RTP (which isn’t specified), but doesn’t actually indicate how far the equilibrium goes because there is no way of being certain how much SO3 is made.

my terrible suggestion.
