You are given a "Gold Crown" to determine whether it is made of pure Gold or not. It has a mass of 675 grams when it is weighed in the air. Then it is submerged in oil (with density of 957 kg/m^3), it reads 640 grams. 7. Find the density of the Crown. Compare to the Gold density 19320 kg/m^3, is it really pure Gold?
When Forrest Gump "just felt like runnin", it is estimated he ran 3.0634 x 10 km. Assuming an average running speed of 6.00 mph and Forrest ran 12 hours a day, how many days was he running? (1milc = 1.60934 km)
Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 8 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000054 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL Do not include units with your answer.

01. [02.01 The Atomic Theory of Matter / 02.02 The Discovery of Atomic Structure] [Answer: (a) Get the answers by yourself. (b) The charge on an electron = 9.60 × 10-9 wa, (c) A: 4e, B: 5e, C: 3e, D: 9e, (d) 6.00 x 107 wa/C.] Suppose a scientist repeats the Millikan oil-drop experiment but reports the charges on the drops using an unusual (and imaginary) unit called the warmomb (wa). The scientist obtains the following data for four of the drops: Droplet Calculated Charge (wa) A 3.84 x 10-8 (a) If all the droplets were the same size, which would fall most slowly through the apparatus? B 4.80 × 10-8 (b) From these data, what is the best choice for the charge of the electron in warmombs? C 2.88 x 10-8 D 8.64 × 10-8 (c) Based on your answer to part (b), how many electrons are there on each of the droplets? (d) What is the conversion factor between warmombs and coulombs?
4. Gasoline can be reasonably approximated as C9H20 with a density of 0.718 g/mL. Diesel can be reasonable approximated as C14H30 with a density of 0.763 g/mL. (Both gasoline and diesel are complicated mixtures. These formulas are something like weighted averages of the formulas of the different components, where the weighting is based on various quantifiable behaviors. That is, using these artificial formulas for gasoline and diesel allows one to calculate average properties that match what petroleum engineers might measure.) The enthalpy change from burning one mole of gasoline is -6160 kJ. The enthalpy change from burning one mole of diesel is -7940 kJ. Determine which fuel generates the biggest enthalpy change per gram burned, and which generates the biggest enthalpy change per mL burned.
The world population is estimated to be 7.4 x 109. Nauru is the smallest island nation and comprises 1.5 x 10-4% of the world population. If the percentage of left-handed people is approximately 12%, estimate the number of left-handers on the island of Nauru.
