Light absorption 2

Question 1

Find conc. of metal ion

Answer 1

• make a graph with two series
• around three values (when the increase starts becoming more subtle) should overlap
• 6-7 values per series
• add linear trendline, equation, R^2 for both data sets

y int of line 2 - y int of line 1 /
slope of line 1 - slope of line 2

answer should be the x where two lines intersect
