Magnesium reacts with HCl(aq) to form MgCl2 and H2(g)

____ Mg(s) + ____ HCl(aq) -----> ____ MgCl2(aq) + ____ H2(g)

The following data was collected for the above reaction:

Mg (g) 5% (m/v) HCl (ml) H2 gas produced (ml)

0.50 10 167

0.50 20 333

0.50 30 500

0.50 40 500

0.50 50 500

Using Excel, graph the volume of H2(ml) produced versus volume of 5%(m/v) HCl(ml) [5.00 grams HCl per 100 ml of solution]. Draw the two lines that intersect to give the equivalence point. (You may draw these lines by hand if you do not know how to do this in Excel.)

What does the graph look like? Can you show me the labels on the graph x y axis
