This year, like many past years, you begin to feel very sleepy alter eating a large helping of Thanksgiving turkey. Some people attribute this sleepiness to the presence of the amino acid tryptophan in turkey. Tryptophan can be used by the body to produce serotonin, which can calm the brains activity and help to bring on sleep. a. What mass in grams of tryptophan is in a 0.25-lb serving of turkey? (Assume tryptophan accounts for 1.0% of the turkey mass.) b. What mass in grams of tryptophan is in 0.25 quart of milk? (Assume tryptophan accounts for 2.0% of milk by mass and that the density of milk is 1.04 kg/L.)

In the picture below, determine how many atoms with a radius of 37pm can fit into a 1.00" box. Canvas does not work well with scientific notation, so you should enter your number as a regular number (you might have lots of zeros, hint, hint). So if you found the answer was 6.36x106 atoms, then you would write 6360000. Hint: Do this as a conversion and start with 1.00 inch as your starting number. This problem seems much more complicated, but it is the same problem you have been doing, you just need to make the units match! r=37pm 1.00"
