You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C34H32FEN.O4, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 10.9 micrograms of Fe. What is the mass percent of hemoglobin in your protein sample?

Be sure to answer all parts. Nitroglycerin (C;H;N3O9) is a powerful explosive. Its decomposition may be represented by 4C H;N3O9 6N2 + 12CO, +10H,0 02 This reaction generates a large amount of heat and gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion. (a) What is the maximum amount of O, in grams that can be obtained from 8.00 x 10 g of nitroglycerin? (b) Calculate the percent vield in this reaction if the amount of O, generated is found to be 26.3 g. 0/0
Why is it important, in carbon dating, to consider the ratio of carbon-14 atoms to other carbon atoms, rather than only the number of carbon-14 atoms?
K is 3.30 x 10^-2. If the original amount of lead-210 in a sample is 70.8 mg, how much lead -210 remains after 20.6 years have passed
Iridium‑192 is one radioisotope used in brachytherapy, in which a radioactive source is placed inside a patient's body to treat cancer. Brachytherapy allows the use of a higher than normal dose to be placed near the tumor while lowering the risk of damage to healthy tissue. Iridium‑192 is often used in the head or breast. Use the radioactive decay curve of iridium‑192 to answer the three questions. The percentage of the sample remaining is plotted on the y axis versus the time in days on the x axis. Some of the points included on the decay curve are 0 days 100 percent remaining, 5 days 95.41 percent remaining, 25 days 79.08 percent remaining, 35 days 71.99 percent remaining, 40 days 68.69 percent remaining, 45 days 65.54 percent remaining, 55 days 59.67 percent remaining, 65 days 54.32 precent remaining, 70 days 51.83 percent remaining, 75 days 49.45 percent remaining, 80 days 47.19 percent remaining, 85 days 45.02 percent remaining, 105 days 37.31 percent remaining, 115 days 33.97…
