Last nights HW counts as a graded quiz equal to one RAT, however if you did not do it I will not drop the lowest RAT of the week. I do not drop zeros. I drop da Base!
1: Hand back and Review RAT 1.9
2: Review HW assignment
3: Handback and review Lab 2 – Density of Liquids
This polymer can absorb 800 times its own mass in water thus for every 1 gram of the polymer it can absorb 800 grams of water. Since the density of water is 1 gram for every 1 ml (Density of 1 g/ml) each gram of the polymer can absorb 800 ml. I used about 2 grams of the polymer so I was able to absorb 1600 ml or 1.6 L of the yellow liquid. We also learned that a cube 1cm by 1cm by 1cm can hold 1 ml. A cm cubed equals 1 ml.
1. Please complete worksheet below by placing answers in form below. I did not give you a hard copy. You can print out the questions or you can view it below. All answers must be in the form by 12:00 am Sunday!! or it will be a doughnut! (zero!). Please use your notes or each other to answer. What this assignment is doing is making you study for next week’s CAT 2 (quiz on classification) and DOG 1 (exam on measurement and classification).
