Answer in a Word Document

1) Firocoxib (C₁₇H₂₀O₅S) is the generic name for a prescription veterinary medicine often given to dogs to relieve pain and inflammation caused by arthritis and other joint problems. Bennie, the Great Dane, is given two tablets per day. Each tablet contains 125 milligrams.

• What is the molar mass of firocoxib? Please be sure to show all steps in determining the answer.
• How many moles of firocoxib are there in one tablet? Please show your work.
• How many moles of firocoxib does Bennie take each day? Show all steps to find the answer.

2) Naproxen sodium, also known as Sodium 6-methoxy-α-methyl-2-napthaleneacetate, (C₁₄H₁₃NaO₃), is an anti-inflammatory medication, often used to treat rheumatic or musculoskeletal disorders. Each tablet contains 250 mg of naproxen sodium, and a typical adult dose is one tablet every twelve hours.

• Determine the molar mass of naproxen sodium. Show all steps to find the answer.
• Calculate the number of moles of naproxen sodium in a single tablet. Show all steps to find the answer.
• Calculate the number of moles of naproxen sodium that an adult would have taken if she took two doses of naproxen sodium in one day. Show all steps to find the answer

3) Ammonia gas (NH₃) forms when hydrogen gas (H2) reacts with nitrogen gas (N₂). A laboratory technician carries out this reaction with 4.75 g of nitrogen and gets 3.99 g of ammonia. Make sure to show all work.

• Write a balanced equation for this reaction.
• Calculate the theoretical yield of ammonia.
• Calculate the percent yield of the reaction.(One mole of any gas occupies 22.4 L under certain conditions of temperature and pressure. Assume those conditions for this question.)
