<p>Hey can somebody help me with this one problem please?</p>

<p>Pheromones are compounds secreted by females of many insect species to attract mates. Typically, 1.0 x 10^-8 grams of a pheromone is sufficient to reach all targeted males within a radius of 0.50 miles. Calculate the density of the pheromone (in grams per liter) in a cylindrical air space having a radius of 0.50 miles and a height of 40 feet.</p>

<p>And could you please show your work too?</p>

<p>Thanks so much! I really appreciate your help!</p>

<p>D= m/V
D=1.0*10^-8 g/(40 feet)(.5 miles)^2(pi)</p>

<p>and do some dimensional analysis to convert feet/miles</p>
