My answer is C
Hmm, I think I have it correct, but if you could tag someone, that would be helpful :)
I think you have it right :/
Thank you I hope so!
What do you think the answer is?
They put C
I think you are correct, Bruno102.
Convert the 128g into moles
You tell me.
Multiply that by 2 then convert it to a mass
Yes, I think so.
What you do is you convert mass into moles of SO2, since the ratio of SO2 to SO3 is 2:2 you actually don't need to multiply by 2, so you have the moles of SO3 currently, so you are able to multiply that by the molar mass of SO3 to get your theoretical yield. So you can take your experimental yield and divide by your theoretical yield and multiply by 100 to get your percent
And I got 90% when I did it
