Chapter 2.7, Problem 2.88QAP

Solve each of the following problems:

  1. A glucose solution has a density of 1.02 g/mL. What is its specific gravity?
  2. A 0.200-mL sample of high-density lipoprotein (HDL) has a mass of 0.230 g. What is the density of the HDL?
  3. Butter has a specific gravity of 0.86. What is the mass, in grams, of 2.15 L of butter?
  4. A 5.000-mL urine sample has a mass of 5.025 g. If the normal range for the specific gravity of urine is 1.003 to 1.030. would the specific gravity of this urine sample indicate that the patient could have type 2 diabetes?

(6 pts - 2 pts each part) Although we focused our discussion on hydrogen light emission, all elements have distinctive emission spectra. Sodium (Na) is famous for its spectrum being dominated by two yellow emission lines at 589.0 and 589.6 nm, respectively. These lines result from electrons relaxing to the 3s subshell. a. What is the photon energy (in J) for one of these emission lines? Show your work. b. To what electronic transition in hydrogen is this photon energy closest to? Justify your answer-you shouldn't need to do numerical calculations. c. Consider the 3s subshell energy for Na - use 0 eV as the reference point for n=∞. What is the energy of the subshell that the electron relaxes from? Choose the same emission line that you did for part (a) and show your work.
