Finding an X value with a given Y value
I'm just so confused (and incredibly stupid). I need to use Excel for every lab experiment in my class but every time I have to work on the graph it is just so confusing. Creating the line and labeling it with the data was hard enough. I am being asked to find the concentration of a copper sulfate pentahydrate solution whose absorbance is 0.150 on this line but I don't know how... How do I pinpoint a specific point on the line?
