“uncomfortable.” You can avoid this problem, of course, by taking the other new dietĭrug, Sibutramine hydrochloride monohydrate, which is marketed by a subsidiary ofīASF as Meridia ®. If you eat too much fat while taking Xenical ®, you’re going to be very, very Calculate the molecular weight of this compound. The molecular formula for this wonder diet drug that is supposed to block the uptake ofįat is C 29H 35NO 5. Xenical ® is (S)-2-formylamino-4-methyl-pentanoic acid (S)-1- methyl]-dodecyl ester. Marketed by Roche Pharmaceuticals as Xenical ®. Let’s consider another “miracle drug” with the scientific name orlistat, which is
(a) between 100 and 200 g/mol (b) between 200 and 300 g/mol When this line structure is translated into a chemical formula we get a molecularįormula of C 22H 32N 6O 4S. The structure of Sildenafil is shown below. (a) 4.6 x 10 -23 g (b) 7.3 x 10 -23 g (c) 28 g (d) 44 gĢ-8.The drug for which more prescriptions – and more bad jokes – were written thanĪny drug released recently has the scientific name Sildenafil citrate and the trade name
(c) between 10,000 and 50,000 grams per mole (b) between 1000 and 10,000 grams per mole Protein is 0.335% Fe by weight and each protein molecule contains four iron atoms. Calculate the molecular weight of the oxygen-carrier protein hemoglobin if this (a) less than 100 amu (b) between 100 and 150 amu What is the mass of a molecule of sucrose (cane sugar) that has the formula:Ĭ 12H 22O 11? (H = 1.0 C = 12.0 O = 16.0 amu) (a) between 0 and 100 g/mol (b) between 100 and 250 g/mol The other!) Calculate the molecular weight of cocaine, assuming a molecular formula ofĬ 17H 21NO 4. coca, whereasĬhocolate is extracted from the seeds of the species E. Cocaine is extracted from the leaves of plants of the species E. (a) less than 50 amu (b) between 50 and 80 amu (c) between 80 and 120 amu What is the molecular weight of aspirin, C 9H 8O 4? (AW: H = 1.00 C = 12.0 O = (c) between 100 amu and 250 amu (d) between 250 amu and 400 amuĢ-3. In amu's? (a) less than 1 amu (b) between 1 amu and 100 amu If this sample weighed 100 ng, what was the element's atomic mass Due to its scarcity, only 2 x 10 14 atomsĬould be isolated. Suppose that a superheavy element with atomic number 120 is found on anĮxpedition to Io, one of the moon's of Jupiter. MACROSCOPIC AND THE ATOMIC WORLD OF CHEMISTRYĢ-1.
