Pre Lab quiz

Today we took a pre quiz before performing the Formula of Hydrate lab. I was not here in class on Friday so I had to get the notes from someone else. I didn't recieve teacher instruction so it took me much longer to complete the equation and I eventually ran out of time before completing the problem. I now feel like I understand the process and am confident that I will do good on the quiz tomorrow about the material we've covered this past week. Here's a picture of what we did instead of the lab today with data provided by the teacher.
