Pre-Lab Questions "Counting by weighing" is used in other applications besides chemistry. A hardware store, for example, may sell nails in packages of 500. Similarly, the office supply store probably car- ries boxes that contain 100 paper clips. Do you think someone counts out by hand every nail or paper clip in these products? 1. The average mass of one paper clip is 0.39 g. What is the expected mass of 100 paper clips? 2. A paper clip manufacturer finds it more efficient to package paper clips in 100-gram lots. How many paper clips would be contained in a 100-g package? 3. In designing a label for this package of paper clips, how many paper clips would you rec- ommend the label advertise?

1-arr In a study of the gas phase decomposition of phosphine at 120 °C PH3(g)- →1/4 P4(g) + 3/2 H2(g) the concentration of PH3 was followed as a function of time. It was found that a graph of In[PH3] versus time in seconds gave a straight line with a slope of -2.50×10² s1 and a y-intercept of -3.24. Based on this plot, the reaction i v O order in PH, and the half life for the reaction is seconds. zero first second
For a field ecology project, you count the number of individuals of different ages found in a population during a single time period. There are 100 newborns, 40 1-year-olds, 15 2-year-olds, 5 3-year-olds, and 0 4-year-olds. Use these data to fill in the Nx, Sx, and Ix columns of a static life table.
