Alright, below are screen captures of some work that I'm tackling. They show my attempts and answers at the problems. I would like to know whether I'm correct or wrong and how to correct the mistakes. The one I need most help with is, the one where you're given density and asked to find molecules. Help will be greatly appreciated. Thanks in advance.(adsbygoogle = window.adsbygoogle || []).push({});
