Find a solution to the following design problem (Figure 2.19): What is the average mass of one grain of rice? You must use an electronic scale that measures to the nearest tenth of a gram. Also, your answer must be precise to one percent. Use the steps outlined on the previous page for solving design problems. Try out your solution in class, with your teacher's permission and the right materials. Be sure to write down what you are trying to accomplish, what your constraints are, and what your idea is for finding the answer. Then show how you would follow the steps of the design cycle. Hint: One grain of rice will not register any mass on the electronic scale. The smallest mass you can measure on the scale with one percent precision is 10 grams (0.01x=0.1 g; x = 10 g) por
