To help farmers and gardeners , commercial fertilizers have a big three -number "NPK" label on the bag that gives the amounts of three key plant nutrients: nitrogen , phosphorus and potassium. For example , a bag of "-10-10-10" fertilizer has 10% by mass nitrogen , 10% by mass potassium as potash (K2O), and 10% by mass phosphorus as phosphate (P2O5). Suppose a certain fertilizer has the following composition. What should the first (nitrogen) number on the bag label be? That is, calculate the the percent by mass of nitrogen in this fertilizer. Round your answer to the nearest percent.

Mercury is an environmental pollutant because it can be converted by certain bacteria into the very poisonous substance dimethyl mercury, (CH3)2Hg. This compound ends up in the food chain and accumulates in the tissues of aquatic organisms, particularly fish, which renders them unsafe to eat. It is estimated that in the United States, 241 tons of mercury are released into the atmosphere each year. If only 1.9 percent of this mercury is eventually changed to (CH3)2Hg, how many pounds of this compound are formed annually?
