b. What is the mass, in kilograms, of LNG (assume that LNG is all methane) transported in one tank on a ship?
c. What is the volume, in liters, of LNG (methane) from one tank when the LNG is converted to gas at STP?
d. Write a balanced chemical equation for the combustion of methane in a gas burner, including the beat of reaction.
e. How many kilograms of oxygen are needed to react with all of the methane provided by one tank of LNG?

Tamiflu (oseltamivir), is an antiviral drug used to treat influenza. The preparation of Tamiflu begins with the extraction of shikimic acid from the seedpods of star anise. From 2.6g of star anise, 0.13g of shikimic acid can be obtained and used to produce one capsule containing 75mg of Tamiflu. The usual adult dosage for treatment of influenza is two capsules of Tamiflu daily for 5 days.
a. If black spheres are carbon atoms, white spheres are hydrogen atoms, and red spheres are oxygen atoms, what is the formula of shikimic acid?
b. What is the molar mass of shikimic acid?
c. How many moles of shikimic acid are contained in 130g of shikimic acid?
d. How many capsules containing 75mg of Tamiflu could be produced from 155g of star anise?
e. What is the molar mass of Tamiflu?
f. How many kilograms of Tamiflu would be needed to treat all the people in a city with a population of 500000 if each person consumes two Tamiflu capsules a day for 5 days?
Select the container that represents the dilution of a solution to give each of the following:
