Serial Dilutions

Royality · 29 Mar 2006 at 19:54

Can anyone help me with some serial dilutions at all? I just can't get my head round them...

So I start with a 1mol solution of Copper Sulphate and want to get the measurements of 0.5,0.4,0.3,0.2,0.1 and 0.0mol solutions by adding distilled water. I also want the simplest ratios producing the smallest amount of Copper Sulphate overall.

i.e: Ratio of 5:5 makes 0.5mol CuS04, overall 10cm3.

I hope you get me, can someone plllease help me. I really need help with this.

Cheers.

Sorry, I didn't explain it clearly. :rolleyes:

What I mean is how to get 0.4mols /dm3 from 0.5mols /dm3, 0.3 from 0.4, 0.2 from 0.3 and etc.

I seeeee, I'll try figuring the rest out for myself, If I can't figure it out though Ill probably beg for help.

Aaaaaarg I still can't do it.

I'm being really rude here but could you write down the ratios for me?

I understand the ratio for 0.5 to 0.4 in 8 parts 0.5 and 2 parts water right? :confused:
