How many kilograms of oseltamivir would be needed to treat all the people in a city with a population of 400000 people if each person consumes two oseltamivir capsules a day for 5 days? Express your answer to one significant figures and include the appropriate units. Oseltamivir, C16H28N2O4, is a drug that is used to treat influenza. The preparation of oseltamivir begins with the extraction of shikimic acid from the seedpods of star anise. From 2.6 g of star anise, 0.13 g of shikimic acid can be obtained and used to produce one capsule containing 75 mg of oseltamivir. The usual adult dosage for treatment of influenza is two capsules of oseltamivir daily for 5 days.

300 kg

Explanation:

The number of people in the city, p = 400,000

The number of capsules of oseltamivir each person consumes per day, n = 2 capsules

The number of days each person consumes the oseltamivir capsules, t = 5 days

The mass of oseltamivir in each capsule, m = 75 mg

The mass of oseltamivir needed to treat all the people in the city, M, is given as follows;

M = n·t·m·p

∴ M (in milligrams) = (2 × 5 × 75 × 400,000) mg = 300,000,000 mg

1,000,000 mg = 1 kg

∴ 300,000,000 mg = 300 kg

The mass of oseltamivir needed to treat all the people in the city, M = 300 kg

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
