Determining the Solute Concentration of a Potato Aim: In this investigation I am going to work out the sugar concentration of a potato. I aim to find this out by putting potato cores into various concentrations‚ measuring the mass before and after. Due to osmosis the potato cores will change in mass to make the concentrations at an isotonic level‚ helping us to work out the mass of the potato. I predict that potato in the weaker solutions will gain mass‚ because some water will be absorbed by the

Statistics involves the development of methods and tests that are used to quantitatively define the variability inherent in data‚ the probability of certain outcomes‚ and the error and uncertainty associated with those outcomes. Some statistics are biased‚ some are based on opinions‚ and some are fabricated. A common misconception is that statistics provide a measure of proof that something is true. Instead‚ statistics provide a measure of the probability of observing a certain result. It is easy

In this report‚ the concentration of total protein and albumin were calculated with the interpretation of a standard curve. To determine the concentration of total protein in human serum‚ a total protein assay was performed by using the Biuret reagent. Proteins react to this compound because it contains two amide bonds. When the Biuret reagents is introduced to a sample of protein‚ it forms a blue or violet complex. The concentration of albumin in human serum is determined by using the Bromocresol
