Which of the following samples has the greatest population density? a. 125,000 organisms in 2.5 mi2028-02-04-03-00_files/i0170000.j pg b. 13,000 organisms in 1.0 mi2028-02-04-03-00_files/i0170001.j pg c. 150,000 organisms in 4.0 mi2028-02-04-03-00_files/i0170002.j pg d. 100,000 organisms in 0.5 mi2028-02-04-03-00_files/i0170003.j pg

 the correct choice is d) 100000 organisms in 0.5 miles.

Explanation: Population density is directly proportional to the number of species(organisms) and inversely proportional to the land area.

population density = number of organisms/land area

Let's plug in the values for all the choices and see which one gives greatest population density.

a) population density =  = 50000

b) population density =  = 13000

c) population density =  = 37500

d) population density =  = 200000

From above calculations, the greatest population density(200000 organism per mile) is for the last choice.

So, the correct choice is d) 100000 organisms in 0.5 miles.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is
