A solution containing $0.8330 \mathrm{~g}$ of a polymer of unknown structure in $170.0 \mathrm{~mL}$ of an organic solvent was found to have an osmotic pressure of $5.20 \mathrm{mmHg}$ at $25^{\circ} \mathrm{C}$. Determine the molar mass of the polymer.

Calculate the molar mass of naphthalene, the organic compound in "mothballs," if a solution prepared by dissolving $5.00 \mathrm{~g}$ of naphthalene in exactly $100 \mathrm{~g}$ of benzene has a freezing point $2.00^{\circ} \mathrm{C}$ below that of pure benzene.

Organic chemists often purify organic compounds by a method known as fractional crystallization. An experimenter wanted to prepare and purify 4.85 g of aniline. Ten 4.85-gram specimens of aniline were prepared and purified to produce acetanilide. The following dry yields were obtained:

$$3.85 , \quad 3.88 , \quad 3.90 , \quad 3.62 , \quad 3.72 , \quad 3.80 , \quad 3.85 , \quad 3.86 , \quad 4.01 , \quad 3.82$$

Construct a 95% confidence interval for the mean number of grams of acetanilide that can be recovered from 4.85 grams of aniline.

Think about all the synthetic materials you use every day. Write a story about being suddenly transported into a society whose only organic compounds were made naturally. How would your life change?

Wen organic waste is dumped into a pond, the oxidation process that takes place reduces the pond's oxygen content. However, given time, nature will restore the oxygen content to its natural level. Suppose the oxygen content t days after organic waste has been dumped into the pond is given by $f(t)=100\left(\frac{t^{2}-4 t+4}{t^{2}+4}\right)$ $(0 \leq t<\infty)$ percent of its normal level. a. When is the level of oxygen content lowest? b. When is the rate of oxygen regeneration greatest?

Which formula represents an organic compound? (1) $\mathrm{NH}_3$ (2) $\mathrm{H}_2 \mathrm{O}$ (3) $\mathrm{NaCl}$ (4) $\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}$
