affeine is a substance whose aroma can be detected by the human nose in the smallest amount. The threshold limit is 4.3 × 10^-11 grams per liter of air. If the current price of 25 g of caffeine is PhP 18.1, determine the cost (in PhP) to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of 3.0 × 10^8 ft^3.

The German chemist Fritz Haber proposed paying off the reparations imposed against Germany after World War I by extracting gold from seawater. Given the following data, what was the dollar amount of the gold that could have been extracted from 3.0 m3 of seawater? The price of gold at the time was $0.68 per gram of gold. Gold occurs in seawater to the extent of 5.15 x 1011 atoms per gram of seawater. The density of seawater is 1.03 g/cm3.
The legal limit for chromium in drinking water is 0.10 ppm. What is the maximum permissible mass of chromium (in \mu gμg) in exactly 1.0 cup (8.0 fl. oz.) of drinking water? Assume the density of drinking water is 1.00 g/mL. (1 fl. oz. = 29.57 mL)(Express your answer with two significant digits.)

Consider Molecule X, which is found in all living cells. This single-strand nucleic acid folds into a compact shape and forms a large complex with about 80 proteins. This complex is responsible for synthesizing new proteins in a living cell. What is the name of X? Your answer should be one word, or a short two- or three-word phrase. Spelling counts. Note: if there is more than one possible answer, separate each answer with a comma. ☐ ×
A calibration curve constructed from absorbance values of solutions containing a known concentration of permanganate ions has the following best-fit line: y = (3.62 × 103 L/mol) x where y is the absorbance of the solution at 525 nm and x is the concentration of MnO4– (aq) in mol/L. The pathlength of the cuvettes used in the experiment is exactly 1 cm. Using this information, what is the molar absorptivity of MnO4– (aq) at 525 nm?
At first, it seemed like the poisoned Russian agent might have ingested thallium in the form of thallium(I) sulfate, a rodenticide (rat poison), not allowed in the US and Western countries but still used in other countries. Thallium leads to hair loss. It also replaces potassium in important enzymes in the brain, muscles and skin. It takes 8.0 x 102 mg of thallium ion to kill an average adult. It took a bit of investigating to figure out that the agent was actually poisoned by polonium, a radioactive element, harmful only if it goes into the body. The radioactivity emitted by polonium, alpha particles, can be stopped by skin; but, if ingested, it gets into the blood stream, travels to organs and does lots of damage. The maximum safe body amount of polonium is 7 pg (picograms!) The agent was apparently poisoned with about 10 micrograms. To provide the minimum amount of thallium to kill the average adult, how many mL of 0.45 M solution of thallium(I) sulfate needs to be ingested?…

Suppose you need 6.0 m of Grade 70 tow chain, which has a diameter of 3/8" and weighs 2.16 kg/m, to tow a car. How would you calculate the mass of this much chain? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. mass of chain- 0.0 X H 0²
