Because our teacher is anal like that.

Sorry sorry everyone. I know that was a stupid question. It's just the answer they gave was wrong. Anyway it's 9.6 mol O_{2} * 2 mol of H_{2}O over 1 mol of O_{2} Which came to 19 mol with sig figs. Sorry again. :/

How many moles of H_{2}O_{(g)} are produced when 9.6 mol of 0_{2}_{(g)} react?

Awesome. Thanks! I got the same answer as vincentchan. And other people did too so I just left it at that. I'm so grateful it's been proved otherwise. V.v.v. thankful. :smile:

Thanks yapper for looking at the problem, at least. Anyone else? :cry:

How fast must a pion be moving in order to travel 15 m before it decays? The avg lifetime, at rest, is 2.6 x 10^-8 s. The answer is supposed to be 0.89c This sounds so easy. Like, just plugging in the formula but I'm not getting it. I haven't done relativity in so long. I think I must've...
