"Ammonia is produced to sell as a fertilizer. Nitrogen from the atmosphere reacts with hydrogen gas to form gaseous ammonia at STP conditions. You must produce 1500 L of NH3 per month and the reaction process is 88% efficient. How many L of hydrogen gas must be purchased to meet the 1500 L quota?"
I can't seem to get the right answer...

So, hydrogen comes as pairs, right> H2? And Nitrogen comes as pairs, N2? Right? So, you want to make Ammonia, you got to have one N and three H's right?
So first figure out how much hydrogen you need if it was 100% efficient.
Then you are going to need more than that because some is going to be wasted (12% lost, right?)
Ok so when you have a handle on how much is needed at 100% efficiency - then that represents only 88% of what you need. So divide that by 88 to get how much 1% is, and multply by 100 to get the total amount....
Hope that makes sense! It would be a lot easier to explain this on a chalkboard.
