Okay I am doing this question for chemistry and I'm not sure if I'm doing it right. I have 5.3g of Copper (II) Sulfate Pentahydrate and I am mixing it will 100ml of water. I need to know the concentration of it. I read that it has a molar mass of 249.6, so I got that I have 0.02 moles of it. Then I got that its concentration is 0.2 mol/L after dividing 0.02 by 0.1 (100ml = 1L).

So am I doing this right because it just seems that I'm doing it wrong for some reason. If I am doing it wrong, what did I do wrong?

I am looking to get either a Zune or Sony 8gb Mp3 player. Both are about the same price, so that doesn't really matter to me. I don't want an Ipod because I really don't like them. I use Windows Media Player, do I'd prefer whatever I buy to work well with that. Here are links to the two Mp3 players that I might buy, which do you think is better?

I live in Canada and we just started getting AFL games on a channel that is part of the basic cable/satellite package.

So my question is what team should I cheer for? Make a case for your favourite and then I'll choose a best answer. Also as a bonus question who is the best player/players on that team.

Thanks for the answers, and BTW I watched my first game this weekend between Carlton and Geelong, and I really enjoyed it.

I was just looking at the lyrics for the song Encore by Jay-Z, and i noticed that on top of Shawn Carter and Kanye West being credited for it, John Lennon and Paul McCartney are as well. This makes me think a Beatles song is sampled in it, I'm just wondering what one it is.

In fantasy baseball I have these pitchers, Chad Billingsley, Dan Haren, Jon Lester, Ted Lilly, Adam Wainwright and Javier Vazquez. I can only start five of the six. Wainwright and Vazquez pitch against each other, so I think I'll leave out one of them. Which one should I start next week?
