A piece of foam has a mass of 24.3g and a volume of 7.21 x1^5 mm^3. What is the density of the foam in g/cm^3? Report answer in thousandths place
PROCEDURE
1. On a clean, dry, and flat surface, place a parchment paper, or any non-porous flat sheet.
2. Obtain your medicine tablet. Take note of its mass. [Note: Since this is home experiment and that you might not have a weighing scale at home, assume that given mass of the tablet is pure, with any excipient/(s). For example, a 500 mg ascorbic acid will have a mass of 500 mg as indicated.]
3. Pulverize the tablet into fine powder and trransfer it in a clean and dry vessel or bottle.
5. Add the necessary amount of distilled water to make the desired concentration of stock solution assigned to your group. [Note: Assume that the volume of the solute is negligible compared to the volume of the solution.]
Concentration of STOCK SOLUTION, M
Concentration of DILUTED SOLUTION, M
0.8 M
0.16 M
6. Make sure to place the computations used in the data sheet.

It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu.

Include a description of what made the concept difficult at first, and then discuss what you did in order to better understand the concept.

Suppose that urine samples are taken and analyzed, and the rate of false positive results is 1%. Suppose also that it is too expensive to refine the method to reduce the rate of false positive results.We certainly do not want to accuse innocent people of using illegal drugs. What can you do to reduce the rate of false accusations even though the test always has a false positive rate of 1%?arrow_forward
