The police have made a drug bust and confiscated a large quantity of suspected cocaine. The police bring a sample to you, a forensic chemist, for analysis. The chemical formula of cocaine is C17H21NO4. After analyzing the mystery compound you find that it is 67.296% carbon, 6.991% hydrogen, 4.618% nitrogen, and 21.095% oxygen. You also find that it has a molar mass of 303.35 g/mol. (A) Calculate the mystery compound’s empirical formula.

(B) What is the compound’s molecular formula?

(C) Based on your analysis, would you testify that the mystery compound is cocaine?

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

i think it is true since you can test the answer and can use observations to complete it.

the answers are

c and c
