Thank you so much for your help professor Goldwhite. You really made my studies on general chemistry much easier for that past 30 days. You made my understanding about different parts of chemistry much easier and also you rock professor Goldwhite.

The Extra Example for this lecture will not play for me. My answer is 0.053mol (rounded from 0.05278 using my own data sheet). I hope somebody can verify my answer. I'd like to know if I worked the problem out correctly. Thanks.
