1.  Il faut un enrobage avec un bon goût pour le nouveau comprimé pour fièvre de Micromed. Chaque comprimé sans l'enrobage a une masse de500mg. Des expériences ont montré que l'enrobage ne doit pas faire plus de2/73of the mass of each tablet (otherwise some of the tablet processing machinery doesn't work right). So what is the maximum mass of the coating allowed on a 500-mg tablet? Round your answer to the nearest hundredth.

2.  A mixture of organic compounds is distilling. As the boiling point of each compound in the mixture is reached, the liquid boils at that temperature until the entire compound is gone and then the temperature rises to the boiling point of the next higher boiling compound. Compound-A boiled at60C et maintenant la température a monté à81C and stabilized. The Boiling point of compound-B is0C. From this we can conclude that the boiling point of compound-A is _________________ of the boiling point of compound-B. (Note: Fill in the blank above with a fraction that makes the statement true)

3.  A 500-gram package of growth powder made by Z-Globe contains0.07% yeast extract by mass. What fraction of the powder is not yeast extract?

4.  In a chromatography column (basically a long thin tube) there is carbon dioxide flowing at a rate of22ml/min. If the maximum flow rate for the column is134ml/min, at what fraction of the maximum is the column currently operating? Express your answer as a fraction.

5.  Three labs measured the iron content of an ore sample sent to them by Terra-Chem, Inc. The first lab reported15mg de fer par cm3. The second lab reported a concentration of4/5celui-là et le troisième laboratoire trouva une valeur d'environ1 1/5of the value reported by lab 2. What was the iron concentration reported by lab 3? Round your answer to the nearest hundredth of a milligram.
