- One mole of silicon (6x1023 atoms) has a mass of 28 grams, as shown in the periodic table on the inside front cover of the textbook. The density of silicon is 2.4 grams/cm³. What is the approximate diameter of a silicon atom (length of a bond) in a solid block of the material? Make the simplifying assumption that the atoms are arranged in a "cubic" array, as shown in the figure. Remember to convert to SI units. d =One mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters. c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube? d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?This was wrong. Can you solve this again with these numbers? What is the root mean square velocity, vrms, for Hydrogen molecules (H2) at 20oC?

- You are modeling the concentration of a drug in a person's blood after they take one pill. We assume that after they take the pill the drug enters their blood effectively instantaneously. The drug has first order elimination kinetics. Complete parts (a) and (b). (a) Explain why the concentration of drug in their blood satisfies a differential equation = - k, c with c(0) = cn. Choose the correct answer below. O A. The differential equation for a drug with first order elimination kinetics is = A(t) - ko. As the drug enters the blood effectively instantaneously. There is no further absorption dc dc = - ko. dt after time t= 0, so A(t) = 0. Thus, О в. The differential equation for a drug with first order elimination kinetics is = A(t) - k, c.
