Calibration curve and concentration?

calibration curve and concentration??

The following is all of the data I have from a AAS/FES for water analysis. I need to make the calibration curves for calcium and sodium. and then I have to find the concentration. can someone please help me with this? i know that the Abs values will be one of my axes but I am confused on what my other axes would be. any help will be appreciated!

Calcium (422 nm/2)

Standards: Abs:
10ppm 0.06
25ppm 0.132
50ppm 0.245
75ppm 0.375
100ppm 0.44
Sample: Abs:
Outside Tap 0.295
Kitchen Tap 0.31
Hose Tap 0.23
Drinking Tap 0.23
Kress 0.061
Oaks Kitchen 0.145
Barkley Fountain 0.15
La Fetra Fountain 0.165

Sodium (589 nm/2)

Standards: Abs:
1ppm 0.09
5ppm 0.345
10ppm 0.525
25ppm 0.848
50ppm 1.275
75ppm 1.52
Sample: Abs:
Outside Tap 0.841
Kitchen Tap 0.762
Hose Tap 0.944
Drinking Tap 0.944
Kress 0.034
Oaks Kitchen 1.248
Barkley Fountain 1.208
La Fetra Fountain 1.208

how do I find the concentration?

 

[Borek]

It is given for your standards, isn't it? Or are you looking at something different from what you have posted?

ohhhhh! so my calibration curves are only going to be of the standards, right? because everything that I posted is all the data I have.
