The following problem can be solved by the concept of molar mass. Concept introduction: The molar mass is defined as the mass of a chemical substance (element or compound) divided by amount of the substance. It is expressed in kg/mol (SI units). The molar mass of a chemical compound is the sum of standard atomic masses of all the atoms present in the compound, which is then multiplied by the molar mass constant (1 g/ mol). Given: In this question, it is given that Tamiflu (Oseltamivir), an antiviral drug used against influenza, is prepared from shikimic acid obtained from star anise. 75 mg Tamiflu (1 capsule) can be produced from 0.13 g of shikimic acid which is obtained from 2.6 g star anise. The adult doseof Tamiflu against influenza is two capsules daily for 5 days. We are asked to find out (a) the formula and (b) molar mass of shikimic acid. (c) Also, we need to find out the number of moles of shikimic acid in 130 g of shikimic acid. (d) We also need to determine the number of capsules of Tamiflu which can be produced from 155 g of star anise. (e) We also need to determine the molar mass of Tamiflu. (f) We need to determine the amount of Tamiflu needed to treat 500, 000 patients (recommended dose - two capsules/ day for 5 days).
