Osmosis

In this lab calculate there ar two tables that I turn out uploaded. I have written lab report because this is a report of a lab, but still not what they are supposed to look like. It is more raw info and conclusion, but I have not added the materials and hypothesis and so on.

Lab with OsmosisResults:Tab.1 shows the weight of carrot slices, before and after manipulation in various concentration of Sodium Chloride (NaCl)In Tab.2 I have shown the role difference of the carrot slices weight after treatment with Sodium Chloride (NaCl). As you can see, there were different groups, and pickings the mean of them all gives us a more slender and accurate description of the results.

Formula used was when evaluating the mean of the persona changes. You had to take the (Sum of the changes in one concentration)/(The amount of groups). When for example scheming the value of the mean in 00.00% concentration NaCl, you had to take (01.77+10.25+04.79+03.58+02.72+04.33+03.15+04.37)/(7)= 30.59/7= +4,37%Conclusion and Evaluation:Well, as we can see on the tables above, using a Sodium Chloride (NaCl) solution with a percentage higher than about one makes the carrot slices hypotonic, since the carrot electric cells go forth take up water from the solution so that the solution gets an equal amount of water as Sodium Chloride (NaCl).



This result make the carrot gain weight, since it has taken in a lot of water, and the cell has then become turgid.

Since we see that with a Sodium Chloride (NaCl) concentration of one percent, the carrot slices have except gained +00.25% of its original weight. And if we therefore increase the concentration with about +00.10%, the cell should reach a point where the cells becomes isotonic, meaning that there are the same amount of Sodium Chloride (NaCl) inside as distant the...
