In conclusion, the objective of the experiment was achieved, and the SWIS mixture was successfully separated into its individual substances. There was a .31 grams difference and only a 3% error, meaning the final mass of 10.40 grams varied 3% from the original mass of 10.09 grams, which reveals that not much error was made in finding the mass of each substance. This lab applies to the real world in that it is useful for someone purifying water because he/she would know to filter it to separate the

osmosis moves across a dialysis membrane. The sub-purpose was to determine if the sucrose solution, that was in dialysis tubing would leak into the distilled water. The hypothesis states that if a sucrose solution, in dialysis tubing, is placed into a beaker filled with distilled water the net movement of sucrose will be into or out of the dialysis bag. The null hypothesis states that if the sucrose solution in a dialysis bags mass may change after taking it out of the water each time to be weighted

1. 2 observations and 2 inferences a. There were 3 different lengths of strings used 1 washer was used The washer is made of copper. They used hemp string in the scenario b. 1 tablet was used. 1 cup of water was used The tablet is alkaline base The water has some levels of acid in it. c. Point A has a population size of 300. Gen 15 has a population size above 400. Point B is the Baby Boom generation. The population needs to be over 500 to be consider a substantial size. d. Enzyme A at 20 Celsius

the more light is absorbed by the solution. Next, we studied color and wavelength and found that solutions of different colors transmit and absorb at different wavelengths. Lastly, by conducting all of these experiments, our group has become efficient and consistent while using the Spec20. We used the guide on how to use the Spec20 found on Canvas. By mastering these goals, we are ready to further study the phosphate concentration

Conclusion: From my results and the above graph I can see that at 0.4 molar there is no loss or gain in the weight of the potato- a 0% increase in weight. This shows that the concentration of the solution is the same as the concentration in the potato. From this I can conclude that the concentration inside the potato is 0.4 molar. These findings supportmy prediction however I was not sure of the exact concentration and now I have a better estimate, but the general trend is the same. The general trend

For a uniform absorbing medium (solution: solvent and solute molecules that absorb light) the proportion of light radiation passing through it is called the transmittance, T, and the proportion of light absorbed by molecules in the medium is absorbance, Abs. Transmittance is defined as:

conditions. Staphylococcus. Epidermidis in 1% NaCl solution had a large amount of growth and the solution was slightly cloudy, 4% NaCl solution had moderate growth, 10% NaCl solution had a small amount of growth. Saccharomy cerevisiae in 1% NaCl solution had a moderate amount of growth with the solution cloudy throughout, in 4% NaCl solution with minimal growth with the growth adhered to the side of the tube, scant amount of growth in the 10% NaCl solution. The test showed that S. epidermidis and S.

dozen cleaning solutions, which resulted in significant product waste and dollars lost as the cleaning staff was using more than one product per job. In addition, the solutions were not environmentally friendly, creating a negative cumulative effect on the staff and the environment. "We've always been an environmentally minded organization, yet struggled to find 'green' products that could get the job done," said Dan Koenig, Facilities Services with TriMet. "While our old solutions worked, we were

point one can begin to help the systems analyst elaborate on possible solutions for these problems. The other possible option is to layout all the different feasible solutions to implement upgrades and begin to aggressively interrogate each solution; this is a process the military calls war-gaming. This process lays out all the solutions and then begins to put the solution through different scenarios and determines if the solution
