Hi, I m unsure whether or not this should perhaps be in the homework forum, however one might say this is more of a technical issue. I recently conducted an experiment for a report I intend to write up promptly, and I wanted to find the best fitting curve for these values. I tested how different salinities affect the degree of absorption of Polyacrylic acid. This is what I found
Trial 1 Trial 2
Salinity 0M 558g 533g
0.25M 95g 93g
0.5M 79g 79g
0.75M 63g 67g
1M 54g 60g
original mass of the polymer was 3g.
Essentially what I would love to find out is how I might be able to get a best fit curve for this graph.
Help would be much appreciated![Smile :smile: :smile:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
