A sample containing 1.20 moles of helium has a volume of 32.0L/ Suppose a leak allows half of the helium atoms to escape, what would be the new volume of the gas sample? (assume P and T remain the same)


I believe that since P and T remain the same then we can use avacadros law were v1/n1=v2/n2
setting v2 by its self

v2= n2*v1/n1

ok I also know that 1.20 moles is n1 and 32.0L is v1 but n2 I dont know. It says that half of the helium atom escaped. do i divide 1.20/2 to get n2??

Face it Democrats, you have no good answer on this. Bush made both Clinton and Kerry look inept and unpresidential.

I know that there are some privatized airports in Europe, but airports in the US are usually run by cities and counties. Do they actually make a profit, or do they need taxpayer subsidy in order to survive?

A book containing testimonies of your brothers and sisters all over the world? I am starting a business and this is my theme. I want to know though if my fellow Christians will be willing to read it. Maybe even a video containing all of the testimonies of persecution and how God changed them. Please let me know

Do you think my doctor will prescribe me tretinoin even though my acne isn't that severe. I don't have a lot of pimples, but just little bumps every here and there. I've been prescribed tretinoin before, but that was last year when I had REALLY REALLY bad acne.

I want to use it again just to prevent acne. I also want to use it to treat my discolored skin and discolored laugh lines(it's darker than the rest of my face probably due to sun damage)

Also are there any side effects to tretinoin because I read on a site that some doctors may be hesitant to prescribe tretinoin because of its side effects.

Thanks in advance and all answers will be appreciated.

Would it be possible to build a hotel where the external walls are made out of sapphire? Sapphire's chemical formula is Al2O3 (the 2 and 3 are subscripts), and it might be possible to synthetically create enough to build a hotel out of. They're making diamonds under high pressure conditions nowadays, so why not sapphires? Mining sapphire would be prohibitively expensive, so it would have to be chemically manufactured. I like sapphires so much, that I might even want a sapphire wedding ring instead of a diamond ring.

It could be called Sapphire Spire, and since it would be so sturdy, it could go up to 30 floors or more!

My boyfriend has told me that he wants to have a threesome with me and he wants to have my friend for a LONG time to be the third participant. I told my friend this (it's a woman) and she was amazed. Now all my boyfriend does is ask my friend all the time if she wants to participate. My question is, does my boyfriend have special feelings towards my friend? He never did pick out any other girlfriend of mine. How do men usually decided if they want a threesome, whom do they want to join? I don't mind the threesome, I just want to know if you think he might like her in some way. Sorry I posted this before, i just need more help. Thanks

Aside from contemporary issues such as creationism vs. evolution, the Bible contains many other simple scientific errors:Leviticus 11:6 asserts that hares chew the cud like cows; they do not.
Deut 14:8 classifies bats as birds; they are not birds, they are mammals
Leviticus 11:20-23 describes flying insects such as beetles and grasshoppers and locusts as having four legs; they have six.
Not surprisingly, those promoting the Bible as the sole authority on science tend to avoid some of these more embarrassing verses
