###### The mercury content of a stream was believed to be above the minimum considered safe- 1 part per bart per billion (ppb) by weight. An analysis indicated that the concentration was 0.68 parts per billion. What quantity of mercury in grams was present in 15.0 $\mathrm{L}$ of the water, the density of which is 0.998 $\mathrm{g} / \mathrm{ml} ?\left(1 \mathrm{ppb} \mathrm{Hg}=\frac{1 \mathrm{ng} \mathrm{Hg}}{1 \mathrm{g} \text { water }}\right)$

##### An annuity is a sequence of equal payments that are paid or received at regular time intervals. For example, you may want to deposit equal amounts at the end of each year into an interest-bearing account for the purpose of accumulating a lump sum at some future time. If, at the end of each year, interest of $i \times 100 \%$ on the account balance for that year is added to the account, then the account is said to pay i $\times 100 \%$ interest, compounded annually. It can be shown that if paymen
