Calculate (using Equation #4 below) the five points indicated in the experiment introduction and show these values in a small table along with one sample calculation. Use Excel to construct a full-page graph of moles H2 per gram sample (NH2) as a function of the % Al. Be sure to include the equation for the line and the R2 value. The slope and intercept should have 4 s.f. (double click on the equation and change the number format to "scientific" with 3 decimals) Make sure to title the graph (with a figure number) and to label the axes properly.
