Chemistry 1010
« on: July 21, 2009, 01:55:48 PM »
How many grams of SO2 are produced when 330 grams of H2S reacts with oxygen?
2 H2s+ 3 O2 arrow 2 So2 + 2 H20

This question is on my homework and the equation is suppose to help me in solving it but I have no idea how to do it! :(

Thanks so much for the *delete me*

No, it isn't. What is the molecular weight of H2S?

Not 330 either. Perhaps another way to look at it - if an egg weighs 34g, how many eggs do you need to weigh 330g?

So how many moles of H2S are there in 330g?

Great! Now, from your equation, how many moles of SO2 are generated when you react 9.7 mol of H2S?

No, not 330. If you had 2 moles of H2S, how many moles of SO2 could you produce?
