Final answer:
The correct molar mass of Firocoxib, the medication given to dogs for pain and inflammation, is 332.27 g/mol, which corresponds to answer choice (a).
Step-by-step explanation:
The generic name for the veterinary medicine given to alleviate pain and inflammation in dogs is Firocoxib, with a molecular formula of C17H20OS. To determine which option is correct for the molar mass of Firocoxib, recall that molar mass is the weight of one mole of a substance expressed in grams per mole (g/mol) or milligrams per mole (mg/mol). Molar mass can be calculated by adding up the atomic masses of each element within the compound as provided in the periodic table.
In this case, the correct molar mass for Firocoxib is 332.27 g/mol. Therefore, from the choices given, option (a) is the correct answer. Bennie the Great Dane is prescribed two tablets daily, each containing 125 milligrams of Firocoxib. Although this is related to the molar mass, it is a dosage and not a measure of molar mass. Notably, COX-2 selective inhibitors like Firocoxib are preferable in certain instances as they may present fewer risks of gastrointestinal problems compared to older NSAIDs.
