A. Click on the return button to go back to the first screen. Then click on the advance button to return to the second screen. Click on the start button to collect a second set of data.

Repeat this process until you have six sets of data. Record these data in the table below.

II. Data Analysis Interpretation and Conclusions

A. What chemical substance is represented by the initial mass? What chemical substance is represented by the final mass? What chemical substance is represented by the change in mass?

B. Plot a graph of the initial mass by the change in mass and determine the equation of the line. Record you results below. Include the graph in your report. (If you have a straight line you can use the equation for a straight line (y = mx + b). If the line is a curved line you can test to see if the plot is a power function (y = x2) or a logarithmic function (y = log x). This can be made easier if you are using a graphing or data analysis program like Excel^TM..)

C. Rewrite the equation to represent the mass relationships between chemical substances. (substitute chemical formulas for x and y.) What does the slope of the line represent.

D. Determine the value for x in the formula CuSO4(H2O)x. (Remember that x is numbers of particles not mass.)
