I love you Dr Bob, you are great. I didn't realise how much it was getting me down. Don't like to give up on something, my text books don't make it very easy to follow through a problem. Understand it perfectly now, I feel so much better now. Thank you very much.
One more thing if I have to give the answer to the nearest whole number 1.77 does that give it a pH of 2?
